HIH-4030 Humidity Sensor Carrier

Sparkfun’s carrier board for the HIH-4030 relative humidity (%RH) sensor from Honeywell outputs an analog voltage that varies nearly linearly with humidity. It operates at 5 V while drawing only 200 μA and has a 0.1" pin spacing that makes it compatible with standard breadboards and perfboards.
