HIH-4000 Series Humidity Sensor

The HIH-4000 Series Humidity Sensors are designed specifically for high volume OEM (Original Equipment Manufacturer) users. Direct input to a controller or other device is made possible by this sensor’s linear voltage output. With a typical current draw of only 200 μA, the HIH-4000 Series is often ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM
production calibration costs. Individual sensor calibration data is available.
