WATERPROOF TEMPERATURE SENSOR DS18B20

Waterproof Temperature Sensor DS18B20
The Waterproof Temperature Sensor DS18B20 is the waterproof version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is rated up to 125°C the PVC jacket soften at around 80°C. Because they are digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-****og converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.
