This SparkFun breakout board houses the Honeywell's HIH-4030 humidity sensor. The HIH-4030 measures relative humidity (%RH) and delivers it as an analog output voltage.


Description [Hide]

Need to measure humidity? It's simple with the Honeywell HIH-4030 breakout board by SparkFun. We've seen this project used in a local science fair project (green house monitor), and it works brilliantly at good value.

Connect the sensor output directly to an ADC on a microcontroller and scale the near-linear analog voltage to the humidity scale. That's it!

Voltage applied to the supply pins should be within 4-5.8VDC, and optimally at 5V. The sensor will typically only consume about 200μA.

This product comes as shown in the picture, with the HIH-4030 soldered onto the breakout board. The pins of the 3-pin header are spaced by 0.1".

Features:

  • Near linear, analog output
  • 4-5.8VDC voltage supply
  • All pins broken out to a 0.1" pitch header
  • Laser trimmed interchangeability
  • Low power design, typical current draw of only 200μA
  • Enhanced accuracy
  • Fast response time
  • Stable, low drift performance

Dimensions: 0.75 x 0.30 " (19.05 x 7.62 mm)
