DS18B20 Water Proof Temperature Probe

This is DS18B20 Water Proof Temperature Probe – Black (1m) Original Chip which is based on the DS18B20 sensor.

It is very handy for when you need to measure something far away, or in wet conditions. Because they are digital, you don’t get any signal degradation even over a 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-analog converter.
