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.

This breakout board for Honeywell’s HIH-4030 humidity sensor from SparkFun measures relative humidity (%RH) and outputs the result as an analog voltage on the pin labeled OUT. The sensor output can be read by an ADC on a microcontroller and varies nearly linearly with humidity, which makes the readings easy to process. The humidity sensor is powered with 5 V and typically draws 200 μA. The pins on the board have a 0.1" spacing, making them compatible with 0.1" male header pins and standard breadboards (Link: www.pololu.com/catalog/category/28) and perfboards. Since this board is a carrier for the HIH-4030, careful reading of the HIH-4030 datasheet (Link: www.pololu.com/file/download/HIH-4030-datasheet.pdf?file_id=0J324) (237k pdf) is recommended.
