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&#39;s near linear voltage output, the data is very easy to process.<br /> <br /> Voltage applied to the supply pins should be within 4-5.8VDC, and optimally at 5V. The sensor will typically only consume about 200&mu;A.<br /> <br /> 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&quot;.<br /> <br /> <span style="font-weight: bold;">Features:</span></p> <ul> <li> Near linear, analog output</li> <li> 4-5.8VDC voltage supply</li> <li> All pins broken out to a 0.1&quot; pitch header</li> <li> Laser trimmed interchangeability</li> <li> Low power design, typical current draw of only 200&mu;A</li> <li> Enhanced accuracy</li> <li> Fast response time</li> <li> Stable, low drift performance</li> </ul> <p> <span style="font-weight: bold;">Dimensions:</span> 0.75 x 0.30 &quot; (19.05 x 7.62 mm)<br /> <br /> <span style="font-weight: bold;">Documents:</span></p> <ul> <li> <a classname="" href="http://www.sparkfun.com/datasheets/Sensors/Weather/HIH-4030_Breakout-v10.pdf" name="" target="_blank">Schematic</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/Sensors/Weather/SEN-09569-HIH-4030-datasheet.pdf" name="" target="_blank">HIH-4030 Humidity Sensor Datasheet</a></li> </ul> Humidity Sensor - HIH-4030 Breakout http://www.sparkfun.com/products/9569 Humidity Humid Humidity Breakout GND
