This temperature sensor is specially designed to work immersed in liquids.
It is made of steel and has a waterproof coating that is also applied individually on the cables.
Within the sensor there is a 18B20 chip which communicates with only one cable that can be shared by various sensors, so that different temperature readings can be obtained using only one pin.
The reading resolution can be set in increments between 0.5 ºC and 0.0625 ºC.
The wiring must be carried out as follows:
• Red (optional, voltage between 3 and 5.5 V)
• Yellow (data)
• Black (ground wire)
Operating range: -55 °C ~ +125 °C
The complete documentation is available on the manufacturer's website, and there are libraries and plenty of tutorials that show how to use the sensor with an Arduino platform.
