Humidity Sensor - HIH-4030 Breakout

The Humidity Sensor (HIH-4030) Breakout board from Sparkfun is a breakout board containing the Honeywell's HIH-4030 humidity sensor. The HIH-4030 humidity sensor measures relative humidity (%RH) and delivers it as an analog output voltage. You can connect the output of the sensor directly to an ADC on a microcontroller and, thanks to the sensor's near linear voltage output, the data is very easy to process.

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 of the Humidity Sensor (HIH-4030) Breakout board:

  • 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)
