Honeywell HIH-4010/4020/4021 Series

The HIH-4010/4020/4021 Series provides high-quality relative humidity (RH) measurement in a cost-effective, solderable SIP (Single In-line Package) housing. With a typical current consumption of just 200 µA, these sensors are ideally suited for battery-powered, low-power applications.

The sensor element’s multi-layer construction offers excellent resistance to common application hazards such as moisture, dust, dirt, oils and typical environmental chemicals.
