Waterproof DS18B20 Digital Temperature Sensor for Arduino (IP68, -10°C to +85°C) Category_Gearmotors/40mm Planetary Encoder the secondary generation pH meterThis 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 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! The DS18B20 provides 9 to 12 bit (configurable) temperature readings over a 1 Wire interface so that only one wire (and
