Honeywell HIH-4010/4020/4021 Series
The HIH-4010/4020/4021 series provides high-quality relative humidity (RH) measurements in an inexpensive, solderable SIP (Single In-line Package) housing. With a typical current consumption of only 200 µA, the HIH-4010/4020/4021 series is ideal for battery-powered systems with low power consumption. The multi-layer construction of the sensor element offers excellent resistance to most application hazards such as moisture, dust, dirt, oils, and common environmental chemicals.
