Waterproof DS18B20 Sensor Kit

A waterproof DS18B20 digital temperature sensor kit with everything you need to connect to an Arduino. The stainless steel probe measures temperatures from -55°C to +125°C over a 1-Wire interface, requiring just one digital pin for communication. Multiple sensors can share the same data pin thanks to unique 64-bit IDs.

The kit includes a terminal sensor adapter for easy plug-and-play connection to Arduino — no breadboard wiring required.
