Still using a dht ... perhaps take a look on the bme280! Temperature, humidity and pressure - from Bosch. Best environment sensor i know for 3€ on an breakout board.

Being able to see your formula in that spreadsheet was great! Love this project

Nice project, you also edit your videos very well, I had a laugh when you dumped the brick on the table!

If you want to slightly reduce connection time of esp to wifi and save some energy you can use a static ip instead of dynamic. BTW, a project is awesome! :-)

I recommend protecting the PCBs from water damage (there will be condensation inside the open tube) with either conformal coating or something like CorrosionX which I used successfully in the past to protect boards exposed to elements. One thing to keep in mind though is the barometric sensor, you will damage it if something gets inside metal housing. Otherwise you will inevitably have burnt boards when condensation inside the tube causes a short circuit.

Thank you for sharing this project

I have just started this project. I already have the brick. LOL

Well done, very good video. I`ll research your project page as I`m sure I`ll get lots of ideas for myself.

Thank you for this! I've been trying to make my weather logger and failed. I'll take a look at yours closely for advice! Great help my friend 👍

Hallo Maker, toll gemacht, sehr gut erklärt und umgesetzt. Es hat richtig Spaß gemacht dieses Video anzuschauen. Ich wollte mir schon lange eine Wetterstation bauen, bin aber trotz gleiche Komponenten nicht sehr weit gekommen. Jetzt wo Du eine gute Vorlage geboten hast werde ich Dein Projekt nachbauen. Der einzige das mir fehlt, ist die Wind Messung mit Amplitude und Richtung. Vielen Dank das Du dieses Projekt mit uns teilst. Danke

another well described project. With PV panels of less than 5 watts i just shunt across the panels with a zenner.

The battery lifetime will be reduced when keeping the cell voltage at maximum all the time. Recommendations for lithium manganese cells (max 4.2V) is to charge them to only 4.1V to increase lifetime. The capacity however might only be at around 80% then. You can lower the floating voltage of your lifepo4 too.

What's the part number of that brick? Can I use any 100MHz brick? This is the best tutorial by the way... I watched them all.

Silicone conformal coating on the boards would work well and you can work on the board again loved the project

I think its best tutorial i found, but actually i am looking with a BH1750 module for LUX readings for the light sensor. all the best!

I am testing the solar + lifepo4 + solar of this setup on low battery levels. I discovered that, when on low battery, the wemos wouldn't start up properly resulting in constant high current draw (no deep sleep) which in turn results in emptying the battery even faster. Adding a 1000uF capacitor resolves this issue extending the setup to run on battery longer. That could just save that one day extra without solar power. I also added a connection to the analog input of the wemos (not using the analog light sensor) from the battery positive terminal (with a 100k ohm resistor as voltage divider) to measure the battery voltage. This could be used to lower the update frequency when the voltage is dropping.

Your video puts many TV shows to shame! Congratulations!

Really like your channel. Me and my dad were watching your videos and he betted a bottle of "Tokai" that you are from Hungry.

Another excellent video! Thanks!

Hey. interesting project. I'm interested in. How did you make phone applications to see these sensors?

Great job bro !!

Nice project man! I like your channel

an excellent channel! keep up the good work!

from where can i get the *brick* ?

Very useful and nice work 🤗 ... waiting for your new video

Hello, this is a good video. I suggest to use a TP-5000 Module, which is capable to charge LiFePO4 cells as well. No needs to be build an additional circuit. Nice job. Oh I just forget to mention you can lowered the power if you use an ATTiny13A. I had a project where the sensor wakes up 4min and 56 secs for 8 secs. the deep sleep period it takes 5.4 [uA]. I use P-Channel and N-Channel MOSFETs to cut of differetn parts....

If you snip off some hot melt glue and put it in the shrinksleeve before shrinking, you make a water tight sleeve. now water is getting in trough capillary action. ... just a hint. Nice work!

You can use a small sugarcube relay, to switch between ldr and battery voltage.. Just keep a default mode like ldr needs to be monitored always.. And whenever you need battery, just power up the relay and your done.. Take a reading and power off!. That's just a suggestion And as always superb videos.. Thumbs up. Thanks for sharing

Excelent. Good job. Thanks

Hello is the project still running would be great to hear how it has survived over two years :). Any damages to sensors?

An interesting contribution, thanks for your effort to publish. Which 3-D-printer do you use?

Hello , awesome videos I’m wondering if is possible to get a notification if some values exceed a value settled ? Thank you for you help ....

i can also recomment such solar lipo charger boards as a powersource for example the "DFRobot Solar Lipo Charger". I connected it directly to the wemos d1 mini 5v and ground pins and it works just fine

Very nice, as always :) Often in your videos I see a nice crimping tool for crimping dupont connectors. Can you write what type it is. They seem to work perfectly. Thanks.

Great sir ....I'm also planning for that which is inspired from u😀 by using node mcu, what is the function of shotokey diode ?

Nice project, i am trying to make one mysefl, this will be great guide video. But add battery level in measurements.

I always have a brick laying around, I can finally use it!

Be careful with skottky diodes. They can have a relatively large reverse current, which kinda defeats their use in Backvoltage protection

Do you have an affiliate link for the brick? It's the last part I need for this project :)

You could also put in some code so that when the battery is near fill and has been receiving good sunlight for the last 2 days or is charging faster than it's losing power than it will update faster.

great video. I would like to suggest using TP4056 Module to charge a li-ion battery. You can plug it into the 5v input without any problems, then you can connect the + side to A0 using 100k resistor. I tried this and its still working for the last 4 months.

So cool!

Brilliant ... Keep it up for this great work ... Could you please tell me what Camera you use ?

How is this project going? is it still deployed outside? and how is the solar panels doing? is it enough to charge ?

Nice video.

Great solution for a WiFi access product. What and how wold you suggest using cell phone in the unit to upload the data?

Fun project thx

This is a very good and awesome Video i Like it verry much .. Thanks

As a newbie I woud like to know if theres anything to take in consideration when buying the zenerdiodes as you havent presented a link to aliexpress?

But there's no rain gauge 😮 How can we know how much it rained? Hope you keep thinking about the power via solar panels! Loved this one. Thank you!

Hey, ich habe deinen Kanal grad gefunden, sehr schöner Kanal :). Was hältst du davon einen CubeSat/ArduSat zu bauen? Vg

Greetings from Darmstadt ;)

Great work Is this station connected to the internet by wifi to a router? Thank you

Hi thanks for this video. I'm wondering how to ensure the wifi range, when my weather station will be setup ca. 50m away from the house. As I'm a rookie in the arduino and esp, I would only ask if there is any possibility to develop some kind of wifi repeater with esp/nodemcu/wemos parts?

Could we use mosfet for diode purposes? It would have less voltage drop, but I'm not sure about the power consumption of the neccesary circuit.

Why doesnt the part list have a link for the brick XD

I know that insert keeps the inside a little isolated, but any sun on that PVC pipe will heat the whole thing up. The open bottom helps, but without any wind there would be a lot of heat build up, and even a decent breeze wouldn't remove all of it. Any extra heat is going to throw all the sensors off. Better to have holes in the top, shielded by an overhang to let air flow through. A 2" or 3" (50 or 75 mm) PVC pipe cap could provide the overhang - just glue it to the cap you have, then drill a bunch of holes in the pipe where the PVC cap will hang past them. You'd probably want to attach a piece of window screen on both ends to keep out dirt and bugs.

Congratulations very good, how to do the same thing but only for the wind speed?

Does the sensor data get published to a cloud service or are you running a web server on the board and just connecting to that with your phone?

Brilliant

so how is going this project? The battery still alive? thanks !

will the code work with the d1 mini pro ?

How this project works now?

Do you also sell a ready version?

Hi guys, and sensei bitluni. I have one issue with this project. Scetch works like a charm, I get readings from DHT22 sensor to serial monitor, but readings are not sent to my server... Inside server runs NodeRed, and I have other ESP8266 with different sketch in it and it forks just fine. Any suggestions for this trouble? Thanks in advance. :)

As u have done this it’s nice but my friend the solar panel which u have used can it be higher

BME280 for sure ... and sigfox to remove wifi consuming and be able to put it nearly where you want

Excellent videos, thanks for sharing, I keep getting "load 0x4010f000, len 1384, room 16 error" is my board fried?,, cheers

as long as you arent continualy trickling it full. i recomend letting it use a small percentage between charging. That will lengthen the charge the most.

But the Batterie and the esp zögertet with the Temperatur Sensor is a good idea? Doesn‘t it make to much Temperatur so the accurancy suffers from it.

would it be possible to buy a cloud ray sensor in this system ??

what are tehe specs of the schottky diode you use?

а мужик молодец, завидую я ему, что у него есть свободное время, на эти увлечения

What's the difference between the Wemos 8525 and esp8266?

Thanks for sharing! What software do you use for your 3D designs? Regards!

What are the stats on that brick there?

How to make Socket Server communication between two ESP32?

Nice.. like the topic :D. still on my wishlist to make. one question though,. you say you are using a BMP180 for air pressure and precize tempreature. what do you mean by that as all the explenations i found for the BMP180 are about barometric pressure and no reference to temprature.

where can i buy the brick ;)

How about using a 4 Channel Analog I2C IC like the ads1115? You could get a higher precision on reading the light level and you could add a batterievoltage reading. Also a Rain/Water-Sensor and a moisturesensor for your Garden would be interesting...

How to control the battery charger so as not to ruin the battery?

will this work with homeassistant?

I'm interested to know why you chose Arduino IDE instead of Mongoose OS for this project? I've been trying out Mongoose OS since finding your videos, and love/hate it so far.

how can you build a mobile app? i mean which platform

bmp180 can also measure temperature

good!

Cool

Du kannst nochmal mehr strom sparen wenn du ein ESP 12 oder 7 Modul benutzt ohne CH340 und die kontroll leds noch weg lässt. Was nochmal strom spart ist einer größere Antenne wenn man keinen so guten empfang hat wird das durch die antenne kompensiert ohne das der Chip die treiberstufe zu sehr hoch fährt.

Technically topping off the battery all the time would be bad. I'm not sure how lifepo4 will handle it. However you are solar charging which means that most of the 24 hours you will be drawing current instead of charging. Then you will be charging and you might get 4-5 hours of topping off, but it won't be every day - especially in the cold seasons. The worst that could happen is that you'll reduce the life of the battery by a bit. But it's not that big deal if you replace it every 3 instead of every 5 years. My biggest concern is if it survived the winters without the voltage dropping too low. Is there a follow up video? I'm curious to see what happened

Hello, have you used another language to program esp8266 such as lua or native espressif rtos SDK? I'm wondering which one is the best for doing this stuff, what do you think? Arduino seems so newbie rs and sometimes buggy

How about making a code directly for esphome ? esphome api is a bit more stable then mqtt ( in my Home Assistant installation 😅 ) Great tutorial ! Thanks

Is it still working?

Are u from Germany?

I just wonder if the weather station still works 4 years later?

Hi, I just played around with MQTT in the last days and had problems to connect the weather station code to the MQTT broker. What worked for me was a change in the feed definition like is is done in the Adafruit Demo, to include the Username in the feed definition like e.g. Adafruit_MQTT_Publish test = Adafruit_MQTT_Publish(&mqtt, AIO_USERNAME "/feeds/test"); Maybe this helps someone else

9:45 Epic moment

AFAIK at least Li Ion batteries don't like to get trickle charged all the time. Nimh cells would be a better choice here... Nice video nonetheless ;)

Why not use the solar panel as a light sensor as it provides power.

Measuring solar panel voltage while it is connected to the battery will only give you the Battery Voltage

Nice project, the potentiometer is drawn wrong on the schematic - unless you intend to use it as a 10k fixed resistor ?
