Raspberry Pi DS18B20 Sensor

День тому

The ds18b20 Sensor Raspberry Pi connection is fairly simple to perform. The ds18b20 is a waterproof one-wire digital temperature sensor with a fair degree of precision.

Once I changed Thonny from micropython to python3 everything worked like you said. Thanks for the code and explanation.

This would be great to monitor my well house temperature.

@raysrcsandtech 3 роки тому

The only tutorial that worked and was explained correctly :)

Hi, thank you for the video. I would be interested in connecting upto 50 devices in a chain. Is that possible? Will there be congestion on the bus? The conversion time is ~90 ms (upto ~800 ms depending on the bit resolution). Does it mean the cycle time for the whole bus would be 50 times 90ms? Or is there a way to send some kind of strobe / sync signal, so that they would all start their measurement at the same time and than read them out sequentially? Thank you.

I already have a Raspbery Pi near the attic from another project (Piaware SDR) and wanted to add another project to it. I was curious to compare attic temperature vs outside. Thanks for producing the straight forward tutorial. It was easy follow.

Glad it was helpful.

Can you connect it to rpi without extension board?

@sfrooze 2 роки тому

Hello, good video, what if i want to connect two sensors for two diferent ambients, is it possible?

@osmankhalid2005 2 роки тому

I want to collect temperature and switch off a relay on certain temperature limit. What should be next steps.

@ObsesiontecnologicaBlogspot 3 роки тому

thanks a lot. It's work perfectly.

@izzyanalytics4145 3 роки тому

You're welcome!

Can I ask a tutorial on how to incorporate it to Spreadsheet then to SMS for a threshold alert?

@netsfear4227 4 роки тому

hi there, does its need to be a 4.7ohm resistor or could I use a 10k one instead? (Great video)

@izzyanalytics4145 4 роки тому

10k should work

Hello Izzy, the sensor which I am using is not getting registered on the PI. everytime there is a different device name in the "/sys/bus/w1/devices"

@Jamesb1735 3 роки тому

can this be done with 13 temp sensors?

@bonefletch2010 2 роки тому

How can I send notifications to my SMS if the temperature surpasses the threshold? Can you help me sir? :(

@guilhermefranco2386 3 роки тому

Hello, First of all I would like to thank you for the video, it was a great help for my college work. How would I be able to export all temperature readings to a log file, instantly? It could be .csv or .txt. Would you have a code like that?

@izzyanalytics4145 3 роки тому

Let me know if this is what you're looking for. If not, there are many ways to do this; I can probably put together a few other examples of needed.

@guilhermefranco2386 3 роки тому

@@izzyanalytics4145 Yes, that's what I'm looking for, but in the video you capture the internal readings of the raspberry, right? I look for how to insert the DS18b20 temperature readings into the open file. thank you for your attention

@izzyanalytics4145 3 роки тому

It's been a while since I've looked at this, but I believe I did something like that here: github.com/israel-dryer/Raspberry-Pi-Sensors/blob/master/ds18b20_logger.py

@izzyanalytics4145 3 роки тому

I'm using f-string formatting, so you'll need to have python 3.6+. Otherwise, all you'd need to do is change the f-string formatting to the `format()` method.

@robertreimann1846 Рік тому

There was no explanation for the resistor.

@matthewbalbis1629 Рік тому

hello what can i do, because whenever i typed cd /sys/bus/w1/devices (enter) then ls the value showed is 00-200000000000? pls help me

@crashhhhhhh3068 Рік тому

I have the same problem, and when I type in those numbers in the next step it says no such file or directory. Did you find a solution to this problem?

@karejonsson8264 3 роки тому

Is this done with Raspberry 3? Will 3B+ work this way?

@izzyanalytics4145 3 роки тому

I used the 3b. Should work fine on the b+

@synonymiumone1003 3 роки тому

I am sending a weatherballon into the statosphere and want to use two sensors to measure the temperature inside and outside of the payload-box :D i just tried soldering the necessary wires and resistors and since it was my first time soldering at all it turned out to be a complete abomination xD But hey, as long as it works

@izzyanalytics4145 3 роки тому

How it turn out?
