This is a breakout board for Honeywell's HIH-4030 humidity sensor. The HIH-4030 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:
- 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: 9.05 x 7.62 mm

0voteA: I?d agree that the datasheet isn?t that helpful. Since it states a minimum load, you need to provide a minimum load of 63uA (I = V / R = 5 / 80000) so an 80K resistor or a lower resistance to give a higher load. If you are trying to keep the current consumption low then you want to get as close to 80K as you can. If you?re running off a power supply then using a 10K or whatever you happen to have to hand should be fine.Posted by on Tuesday, 24 January 2012
