A waterproof digital temperature sensor based on the popular DS18B20 chip. The stainless steel probe can be submerged in liquids or placed in harsh environments, making it ideal for monitoring aquariums, brewing, weather stations, and outdoor projects.

Uses the 1-Wire protocol, requiring only a single data pin to communicate with your microcontroller. Multiple sensors can share the same data line, each identified by a unique 64-bit address.
