HH10D humidity sensor Bus Pirate interface

Anthony posted a tutorial on interfacing  HH10D humidity sensor with the Bus Pirate. He did the hard work of finding the calibration data, follow his tutorial and you’ll save time.

HH10D uses a change in capacitance due to humidity to alter the output pin frequency. The calibration data is stored on a I2C EEPROM.

Two modes of the Bus Pirate were used. He set the calibration data using the I2C mode, and then measured the humidity using the frequency probe.

  1. Hello, is it possible to read HH10D sensor data with the I2C interface on the Raspberry Pi?
