Hi,

Thanks a lot for your suggestion

@boozz
I've tried to connect the DS18B20 in parasite-powered mode. Now it is not warming anymore but the sensor is not detected by any example sketch I have tried (oneWireSearch, Single).

@DrJeff
I've tried your suggestion but it is not helping. My sensor still get warm.

I have 5 sensors and all of them are behaving the same. I have also tried with another arduino but it had the same behavior.

Here is a picture of my sensor. I believe everything is ok.

I hope I didn't buy crap.

Kind regards,

Laurent

Here a a zoom on the DS18B20.
Orange wire is 3.3V, green is D2 and black goes to the ground.

Would it be possible that I mistake the bottom view described into the datasheet?
All example I can see online are connected like this.

I'm using the example sketch named 'Single' coming into the Arduino IDE.

Kind regards,

Laurent

Hi TheoL,

Thanks a lot for your suggestion.

I've changed the VCC of my DS18B20 to get 3.3V coming from a AMS1117 but I still get the same behaviour.
Still getting hot, and the software does not detect anything on the bus.

Would you have another idea what to check?

Thanks a lot.

Kind regards.

Hello,

I'm getting trouble with using my ds18b20.

Basically whenever I'm putting the power inside my Arduino nano, the sensor is getting hot to eventually be burned.

I've already saw online that it can be because of wrong wiring but in this case I'm quite confident I didn't make any mistake. See the picture below:

Does anybody would know what is wrong in my circuit?

Thanks a lot for your help.

Kind regards,

Laurent
