HTF3223

TECHNICAL TEMPERATURE AND HUMIDITY MODULE 1 DATA HF 3223 / HTF 3223 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. MAIN FEATURES G G G G G G Size and connector type match existing humidity modules. Stable, linear proportional frequency output from 10 to 95% RH. Calibrated within +/- 5% RH @ 55% RH. Optional 10 K +/- 3% NTC temperature sensor (HTF 3223) Stable characteristics with temperature. High reliability and long term stability. HF 3223 / HTF 3223 HUMIDITY SENSOR SPECIFIC FEATURES G G G G G Instantaneous de-saturation after long periods in saturation phase. Fast response time. High resistance to chemicals.
