Sensirion SHT85 Humidity & Temperature Sensor

Sensirion SHT85 Humidity and Temperature Sensor is a high-accuracy RH&T sensor for demanding measurement and test applications. The sensor features a pin-type connector for easy integration and replacement with a unique package design that allows for secure thermal coupling to the environment and decoupling from potential heat sources on the main board. A PTFE membrane protects the sensor opening from liquids and dust, according to IP67, without affecting the response time of the RH signal. The Sensirion SHT85 sensor can be used in harsh environmental conditions, including water spray and high dust exposure.
