Now you can build your own room temperature monitor using an Arduino board. The circuit is a combination of an Arduino UNO board, LM35 temperature sensor, and a 16×2 Hitachi compatible LCD. It will ...

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.

This isn’t about connecting a temperature sensor in your Arduino. ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

It reads the current temperature from a LM35 temperature sensor and actuates the valve to bring the wort to a set point. A neat addition to the build is a wireless radio. The nRF24L01 module ...
