High Precision Humidity Sensor SHT75:
Digital, Interchangeable & Fully Calibrated

The SHT75 is a high-precision capacitive humidity and temperature sensor for demanding applications. The sensor comes in a
high quality pin-type packaging (for 1.27mm sockets). Owing
to full calibration and digital 2-wire output (CMOSens®
Technology), the SHT75 is fully interchangeable. In this way,
you are spared the elaborate and cost intensive recalibration
in case of a humidity sensor replacement!

The sensor head is connected to the pins by a small bridge to minimize heat conduction and response time. All pins are gold
plated to avoid corrosion even under the harshest operating conditions.
