Product Description

SHT85 is Sensirion’s best-in-class humidity sensor with pin-type connector for easy integration and replacement. It builds on a highly accurate and long-term stable SHT3x sensor that is at the heart of Sensirion’s new humidity and temperature platform. The unique package design allows for the best possible thermal coupling to the environment and decoupling from potential heat sources on the main board. The SHT85 features a PTFE membrane dedicated to protect the sensor opening from liquids and dust according to IP67, without affecting the response time of the RH signal. It thus allows for sensor use under harsh environmental conditions, (such as spray water and high exposure to dust). Final accuracy testing on product level ensures best performance, making the SHT85 the ultimate choice for even the most demanding applications.
