HIH-4010/4020/4021 Series Humidity Sensors
DESCRIPTION of humidity sensor HIH4010/4020/4021 Series
The HIH-40104020/4021 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 near linear voltage output. With a typical current draw of only 200 µA, the HIH-4010/4020/4021 Series is often ideally suited for low drain, battery operated systems.
