16. One Wrie Waterproof Temperature Sensor
Description
This is a waterproofed version of the DS18B20 Temperature sensor. Handy for when you need to
measure something far away, or in wet conditions. While the sensor is good up to 125 degree,
the cable is jacketed in PVC so we suggest keeping it under 100 degree.
