Version: 2.0
- 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
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.

Calculation
In order to read out the correct humidity, 4 calibration factors need to be read out
from the EEPROM at address of 10 and 11,12 and 13 for sensitivity, offset.
Once the frequency output from the sensor is measured, then the correct
humidity value can be calculated in the following method:

RH(%)=
(offset-Soh)*sens/2^12
* RH(%) linear humidity value
* RH_corr temperature compensated humidity value
* Soh is the measured frequency value at Fout port
the eeprom physical address is fixed to 01.
