SparkFun Humidity Sensor Breakout - HIH-4030

The SparkFun Humidity Sensor Breakout - HIH-4030 is a compact and efficient module designed for Honeywell's HIH-4030 humidity sensor. This sensor measures relative humidity (%RH) and outputs it as an analog voltage. With a near-linear voltage output, the data from this sensor is conveniently easy to process, making it an ideal choice for projects that require precise humidity measurements.

The HIH-4030 operates with a voltage supply within the 4-5.8VDC range, ideally at 5V. It's a low-power design, consuming only about 200μA typically. This makes it an excellent choice for battery-powered applications where power efficiency is crucial. The sensor is already soldered onto the breakout board, ready for use right out of the box.

The pins of the 3-pin header on this product are spaced by 2.54mm, making it compatible with most standard connectors. The breakout board measures a compact 19.05 x 7.62 mm, making it easy to fit into a variety of project designs.

Some of the notable features of the SparkFun Humidity Sensor Breakout - HIH-4030 include its near-linear, analog output, laser-trimmed interchangeability, enhanced accuracy, and fast response time. It also offers stable, low drift performance, ensuring reliable and consistent readings over time.

Whether you're creating a weather station, a home automation system, or any project that needs to monitor humidity levels, the SparkFun Humidity Sensor Breakout - HIH-4030 is a reliable and high-quality choice.
