Temperature sensor suits harsh environments

A temperature and humidity sensor from Sensirion is in stock at RS Components. The SHT85 builds upon Sensirion’s SHT3x series, which offers CMOSens technology that for more than 10 years has delivered highly accurate units with long-term stability.

Adding to these capabilities, the SHT85 comes with a pin-type connector, which enables easy integration and replacement, and offers excellent thermal coupling to its surrounding environment as well as decoupling from potential heat sources on the main processing board.

Able to operate in harsh environmental conditions, the sensor also features a PTFE membrane that meets the IP67 rating.

Designed to protect the sensor opening from water and dust, use of the membrane means the response time of the relative humidity (RH) signal is not affected.

Offering a fully calibrated, linearised and temperature-compensated digital output, other key features of the SHT85 include: final product level testing to deliver a typical accuracy of ±1.5% (RH) and ±0.1°C; an I2C interface with communication speeds up to 1MHz; fast start-up and measurement time; low signal noise; and an operating voltage from 2.15V up to 5.5V.

The Sensirion SHT85 humidity and temperature sensor is now shipping from RS in the EMEA and Asia Pacific regions.
