[Outline]
The MW3827 is a sensor IC in which a relative humidity sensor, temperature sensor, and our proprietary analog front-end are integrated.
Thanks to our proprietary moisture-sensitive film combined with parallel plate capacitance, the humidity sensor unit has excellent durability and reliability.
The front-end unit outputs temperature and humidity measurements in the digital form (I2C) after complete correction, so in combination with an external microprocessor, the MW3827 can function as a sensor without a complicated sensor drive circuit or control circuit.
With its small sensor area and wide operating temperature range, the MW3827 is applicable for home appliances, industrial equipment, and other various sorts of application.
