SHT3x-Series Digital Humidity Sensors for Harsh Environments
Sensirion offers its SHT3x-series of digital humidity sensors with an added filter membrane option
Sensirion's SHT3x-series offers fast and accurate humidity and temperature measurement and now comes with a new filter membrane option for harsh environments. SHT3x-series membrane is an ePTFE type of foil, dedicated to protect the sensor opening from water and dust according to IP67 standards. It will thus allow for sensor use under harsh environmental conditions, where spray water and high exposure to dust is challenging for accurate sensor performance. The membrane cover is attached to the sensor package by a double-faced adhesive tape, which is designed to stay on the package over the whole sensor life-time. Due to the minimum enclosed air volume, the response time of the RH&T signal is identical to the value given for the uncovered sensor.
