Humidity Sensor - Analog

Check this out everyone! It’s a breakout board for Honeywell's HIH-4030 humidity sensor. Wait, but what is HH-4300 and what does it do? It really does a great job at measuring relative humidity (%RH), then it delivers it as an analog output voltage. Data is easily processed since the sensor has a near linear voltage output. All you have to do is to connect the output of the sensor directly to an ADC on a microcontroller.

Supply pins should have an applied voltage that range within 4-5.8VDC, optimally at 5V. Note that the sensor consumes ~200 μA. Also, the HIH-4030 should be soldered onto the breakout board. And last but not least, the pins are spaced by 0.1" among the 3-pin header.

Get it now!.
