HIH61xx is a library for accessing the humidity and temperature data from the I2C range of Honeywell HIH61xx humidity sensors (HIH6120-021, HIH6121-021, HIH6130-021 and HIH6131-021). Do not confuse these sensors with the SPI versions (HIH6130-000 and HIH6131-000).
Software I2C is used to allow this sensor to be connected to any two digital pins. An optional power pin can be used to control power to the device. A state machine ensures the relevant timing constraints are observed.
The following libraries are required AsyncDelay: see https://github.com/stevemarple/AsyncDelay SoftWire: see https://github.com/stevemarple/SoftWire
The HIH61xx_demo sketch demonstrates the state machine operation.
