Electronically it is pretty simple: a Helltech CubeCell AB01 LoraWAN module is wired up with three DS18B20 temperature sensors, a LiPo battery and a solar panel. (The AB01 has the required ...

I think that we can use the type TSOP1838/AH1838/VS1838 infrared receiver module here. It’s noteworthy that the temperature sensor socket’s pin assignment is in the correct order for DS18B20 only.

Now we are going to look at how to use the temperature sensor module with an Arduino. It is quite easy as there’re several Arduino libraries available for playing with them. I used the library ...

Wanting to know the outside temperature, [Jamie Maloway] built his own temperature sensor that can be read with a Bluetooth device. Let’s take a tour of the hardware above from right to left.… ...
