Pin-type Humidity Sensor Enabling Easy Replaceability

Sensirion presents the new pin-type relative humidity sensor SHT85 for easy replaceability in a wide range of applications. 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 relative humidity signal. It thus allows for sensor use under harsh environmental conditions, such as high exposure to dust.

Sensirion’s CMOSens® Technology offers a complete sensor system on a single chip, consisting of a capacitive humidity sensor, a bandgap temperature sensor, analog and digital signal processing, A/D converter, calibration data memory, and a digital communication interface supporting I2C fast mode. The sensor covers a humidity measurement range of 0 to 100% relative humidity and a temperature measurement range of -40°C to 105°C with a typical accuracy of ±1.5% RH and ±0.1°C. The broad supply voltage of 2.15 V to 5.5 V make the SHT85 perfectly suited to a wide range of applications (more info).
