DS18B20 Waterproof Temperature Sensor

DS18B20 Waterproof Digital Temperature Probe

Encapsulated in a corrosion-resistant 304 stainless steel tube with a flexible PVC waterproof cable, the DS18B20 is designed for rugged liquid immersion and soil temperature monitoring. Each sensor has a unique 64-bit serial code, allowing dozens of probes to be chained along a single microcontroller GPIO line.
