DS18B20 Digital Temperature Sensor Gearmotor Specifications:This is a pre wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125C the cable is jacketed in PVC so we suggest keeping it under 100C. 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. 5C over much of the range) and can give up to 12 bits
