HUMIDITY SENSOR MODULE
[attachment=48094]
Summary
The HH10D relative humidity sensor module is comprised with a capacitive type humidity sensor, a CMOS capacitor to frequency converter and an EEPROM used to holding the calibration factors. Due to the characteristics of capacitor type humidity sensor, the system can respond to humidity change very fast. Each sensor is calibrated twice at two different accurate humidity chambers, two unique sensor related coefficients are stored onto the EEPROM on the module. The data is used for humidity calculation.
FEATURES
Relative humidity sensor
Two point calibrated with capacitor type sensor, excellent performance
Frequency output type, can be easily integrated with user application system
Very low power consumption
No extra components needed
