DF Robot Waterproof DS18B20 Temperature Sensor Kit

The DF Robot Waterproof DS18B20 Temperature Sensor is a reliable digital sensor designed for accurate temperature measurement in wet or remote environments. It features a stainless steel probe for enhanced durability and a 1-Wire interface, which allows multiple sensors to share a single data line without signal degradation. This makes it ideal for applications such as HVAC systems, industrial monitoring, and environmental sensing.

With an accuracy of ±0.5℃ between -10℃ and +85℃ and an extended operating range of -55℃ to 125℃, this sensor ensures precise readings in various conditions. It operates on 3.0V to 5.5V and comes with a pluggable terminal sensor adapter for secure and convenient wiring. The 90cm PVC-jacketed cable is suitable for most installations, but it is recommended to keep it under 100℃ for long-term reliability.
