Overview

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 and perfboards. Since this board is a carrier for the HIH-4030, careful reading of the HIH-4030 datasheet (237k pdf) is recommended.
