WHT20 MEMS type Temperature and Humidity Sensor

Principle Introduction:
WHT20 is embedded in a dual-row flat no-lead SMD package, which is suitable for reflow soldering, with 3.0x3.0mm bottom surface and 1.0mm height. The temperature and humidity signals can be read on different pins. The sensor outputs calibrated digital signals in standard IIC format. WHT 20 is equipped with an ASIC chip, a MEMS capacitive humidity sensor and a temperature sensor. WHT 20 temperature and humidity sensors have been calibrated and tested on factory, and have excellent reliability and long-term stability.

Applications :
Home appliance fields: home appliance, humidity control, HVAC, dehumidifiers, smart thermostats, and room monitors etcs;

Industrial fields: automobiles, testing equipment, and automatic control devices;
