This is a breakout board for Honeywellâs 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 sensorâs 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 200?A. 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 output4-5.8VDC voltage supplyAll pins broken out to a 0.1" pitch headerLaser trimmed interchangeabilityLow power design, typical current draw of only 200?AEnhanced accuracyFast response timeStable, low drift performanceDimensions: 0.75 x 0.30 â (19.05 x 7.62 mm)Documents:SchematicEagle FilesDatasheet (HIH4030)Hygrometer Reconditioning NoteBildr TutorialGitHub (Design Files)
