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.

The device is simple — it uses an Arduino ... a Helltech CubeCell AB01 LoraWAN module is wired up with three DS18B20 temperature sensors, ... It eliminates the need for bulky temperature probes ...

The T400 is compatible with a wide variety of K-type thermocouple sensor types from stainless steel probes to rolling surface-contact sensors. The Arduino compatible Pax Instruments T400 ...

I connected one soil probe to power, and the other to ground through a 10kΩ resistor and to Arduino's analog pin A0. I did the same with the thermistor and photoresistor, but connected those to ...
