Hello all ! I have this running, however, the Capacitive sensor drains the battery even with the ESP32 is in deep sleep mode. Is there a way to "wake-up" the sensor when the ESP32 wakes up? (e.g. put both to sleep)

i changed the xiaomi 9a screen and now my device works normal but i cant charge my phone

Get a group that is close, use the bms sized for the correct amps. Use a charger that is designed for lithium ion. I find usbC to be awsome for this as it can autorange 3.6V 7.2V 12V and 20V ❤

The Graphics that I see in the ESP Home is already built in, I mean pre coded in the ESP Home? About 6:14 in the video. Thank You. Nice Project Sir! Keep it Up! I see from what I understand as you say Sir, it displays the reads and translate it based on the template...is there any other template that I may use for a basketball arcade more of a seven segment scoring template for a sensor that can function as a ball counter.

What do you think of using the ESP-01S with those expansion boards like RGB LED, DHT11, etc? I'm testing it with CR123A batteries.

Thank you from New Hampshire, USA

I dont know where all of the makers of this content live, but i haven't seen a single vape pen in the "street" as literally every single video ive seen claims to happen. SO, ive had to take up vaping in order to acquire these batteries😅

Does the simcom require subscription?

hello, do you know how much power does the LoRA module by the NodeMCU board itself? If not, can you suggest me a way how to find it using measuring equipment?

Slow down the fan speed reduces the air flow, not enough heat removal as you say at the end

Great Project, Thank You

Good video 👍 One suggestion I could offer if I may... I have built a similar menu for my garden hydrant controller. I noticed on yours that the display flickers every time you change the values in each submenu. To smooth that out, avoid clearing the LCD for those updates. You only need to reprint the value that changes instead of the entire submenu text. Cheers!

Been wanting to do something similar to keep tabs on the salt level on my water softner.

My power module also stopped after water leaked into it. I would like to know how it could be repaired.

Very cool project. I'm not sure the life expectancy of the laser, but setting the update interval to once a minute or once an hour might be prudent.

Is there such a thing for TikTok too?

This is actually a vactrol, or an optoresistor

Hi, is it possible to have the drawing of the electrical connections? there is so much confusion and so many words

A PTC element is not like a soldering iron element. In a PTC element, there Is a bimetallic heating plate sandwiched between two plates that has the lead wires . Overtime , that bimetallic plate wears, until it wears down so much that it causes a " short circuit" causing the explosion.

Neat thanks!

Does it have app to establish end-to-end communication?

I love how you don't explain a single thing you're doing. Very educational.

Dust dont do well with optics

Can you make a ipad one

Excellent piece of work. Keep it please!

Could you please tell me which transistor you used?

Thanks for the video. I also have a led panel with a dimming problem at start up. I dissembled it and had no idea how to control the current of these drivers. Searched days to find a video on this type of driver. finally found. I had done this in regular LED lamps which worked great... Hope these companies stop frying these LEDs and ripping us off... So much life wasted in LEDs due to overheating.

I have Dusun DS210 and have installed HA on it. I will tell you this, it's not worth getting it. You have to always reinstall every few weeks as HA will stop working and start showing you persistent error when you try to login to HA and the only way to fix it is to reinstall the Debian firmware. Also, for some reason it non-stop ping to baidu that I have to block through host file but I really lose trust as I don't know what it's doing in the background.

please write what mosfet you used

Hi, have you tested it with espnow? Could it last longer since it doesn’t connect to wifi

can you add credit remotely without the card?

How long does it run with one charge?

Do yourself a favour and cover the pcb with hot glue or similar. Otherwise it will be destroyed by the humidity of the soil within 1-2 weeks. I "painted" them with hot glue and worked with a hot air gun to keep the layer thin :) Other than that - interesting project! p.s.: saw on second sight you covered the edge of the pcb. I coverd it completely including the smd components and drove it completely into the earth to have more accurate results.

What does the moisture level correlate to? Is it volumetric water content?

The video is the reason why I love doing things from scratch, it is fun, and you can learn a lot, but also is there a similar cheap version already made that can be connected with an assistant? probably not, so you enjoyed doing it, and also you made a great gadget, nice job!

In prison guys would put 2 bent peices of foil in the socket and place cup of water up to the 2 peices of foil (dinner tray) and boil their water for coffee of tea.

Hello Sir, I have a final year project, which i think is very similar if not exactly what you did because i am not good at mobile development as well. The project is as follows and i will really love your help and assistance with everything as you did yours Project: Design and implementation of a wireless communication platform using IOT: an application for animal tracking. Looking forward to your reply and help. Thank you very much

Came across this while looking for solutions... Turns out cellphone chargers have 5v optocouplers

Hi, fantastic work . What tool did you use to cut the pcb ?

Please updaten the Triac Module is no longer on Aliexpress

In the USA we use 120VAC and I have a large 2.0HP (about 10amps) Inductive AC motor I need to control the the speed of on a table saw. I like you setup. Problem with Triacs is Idle current. So when your circuit is "OFF" how much power is it still drawing ? If I am Drawing 10 amps then would I not need a much bigger heatsink for the Triac ? Would you still use an Arduino node MCU if you did this again ?

why do all my sensors write 755 instead of 530?

Can I use two of these bridges to create a link between two buildings? The primary building has internet and wifi, as well as cabled network. I want to create a WiFi in a secondary building, to connect some WiFi-IOT. My attempt to reuse 5GHz network bridges previously used for a WiFi link between LAN in two buildings, failed miserably. While the previous link was to extend the network requiring decent speed for streaming. This application only requires some connection, for WiFi enabled IOT devices. I basically want to run a long network cable between an Ethernet switch in each building, but it's too far. Switch --- cable --- bridge ---- wireless link ---- bridge --- cable --- switch

Thank you so much for this detailed diy! I love that many times you said I didn’t have it so I did this instead because I won’t have those things either! I will be using this video as a template for my storage cabinet diy! First step is going to Home Depot and asking them if they make the round holes on the melamine for hinges lol thank you so much for this tutorial!

Must try with two yagi antennas on these modules. I made some reliable communication relay with wifi cards at 2.4 GHZ and two yagi at 15 KM with really good bitrate. 915 MHZ must be more than that easily.

What is the power consumption for this? Curious how long this will run off a 10000mah pack? Great video!

Thank you.

This arduino nano is one from aliexpre becausr onlinon aliexpres i seen Both chips

I build drainback system and this is exactly what i was looking for,I cant help with coding but i will share my pcb for this project drive.google.com/file/d/1pU7acg3FPLhypMhG43gnbqHL6DfOiJKJ/view?usp=sharing

Very helpful video. Thanks!
