Humirel Sensor Device Data / HPC014 Rev G July 2001
Based on the rugged HS1101 humidity sensor, HF 3223 / HTF 3223 is a dedicated
humidity and
temperature transducer
designed for OEM applications where a reliable and accurate measurement is
needed. It features a miniature connector for easy, cost-effective mechanical mounting. Direct interface
with a micro-controller is made possible with the module’s linear
frequency output
.
