HTF3000LF Temperature and Relative Humidity Module Small size product Compliant with RoHS recommendations and most of Lead Free Soldering Process Humidity calibrated within +/-3% 55%RH at 5Vdc Stable, proportional frequency output from 0 to 100% RH High quality thermistor DESCRIPTION Based on the rugged HS1101LF humidity sensor, HTF3000LF is a dedicated humidity and temperature transducer designed for OEM applications where a reliable and accurate measurement is needed. It features a very small size for easy, cost-effective mechanical mounting. Direct interface with a micro-controller is made possible with the modules linear frequency output. FEATURES Humidity Sensor Specific Features One of the smallest humidity/temperature modules on the market Instantaneous de-saturation after long periods in saturation phase High reliability and long term stability Fast response time High resistance to chemicals Not affected by water immersion Patented solid polymer structure Stable characteristics with temperature Temperature Sensor Specific Features 10k +/-1% NTC temperature sensor Part could be washed with distilled water Stable High sensitivity APPLICATIONS Printers HVAC controller HTF3000LF HPC077 Rev J www.meas-spec.com October 2012 1/7 HTF3000LF - Temperature and Relative Humidity Module PERFORMANCE SPECS MAXIMUM RATINGS Ratings Symbol Value Unit Storage Temperature Tstg -40 to 105 C Storage Humidity RHstg 0 to 100 % RH Supply Voltage (Peak) Vs 16 Vdc Humidity Operating Range RH 0 to 100 % RH Temperature Operating Range Ta -40 to 85 C Peak conditions: less than 10% of the operating time.
