HTF3000LFPVH TE Connectivity

HTF3000LF PVH-3.3 TEMPERATURE AND HUMIDITY MODULE Compliant with RoHS recommendations Based on the rugged HS1101LF humidity sensor, HTF3000LF PVH-3.3 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. MAIN FEATURES One of the smallest humidity / temperature modules on the market Compliant with RoHS regulation and most of Lead Free Soldering Process Stable, proportional frequency output from 0 to 100% RH Calibrated within +/- 3% RH 55% RH at 3.30 VDC High quality thermistor Stable characteristics with temperature High reliability and long term stability HUMIDITY SENSOR SPECIFIC FEATURES Instantaneous de-saturation after long periods in saturation phase Fast response time High resistance to chemicals Not affected by water immersion Part could be washed with distilled water Patented solid polymer structure TEMPERATURE SENSOR SPECIFIC FEATURES 10 k+/- 1% NTC temperature sensor Stable High sensitivity SENSOR SOLUTIONS /// HTF3000LF PVH-3.3 9/2015 Page 1 HTF3000LF PVH-3.3 Temperature And Humidity Module MAXIMUM RATINGS Ratings Symbol Value Unit Tstg -40 to 105 C Storage Temperature RHstg 0 to 100 % RH Storage Humidity Range Supply Voltage (Peak) Vs 16 Vdc RH 0 to 100 % RH Humidity Operating Range Temperature Operating Range Ta -40 to 85 C Chart1 CHARACTERISTICS Humidity sensor (Ta =23C, Vs=5Vdc, RL >100K unless otherwise stated) Characteristics Symbol Min Typ Max Unit Relative Humidity accuracy (0 to 100 % RH) RH Refer to Chart 2 on page 2 Voltage supply Vs 3.1 3.3 3.6 VdC Nominal output RH = 55 % and 5 Vdc Fout 6419 6455 6491 Hz Current consumption (Max at 16Vdc) Ic 0.1 mA Voltage supply influence (3 to 7 Vdc) RH +/-1 % RH Averaged Sensitivity from 10% to 95% RH Fout /RH -9 - 11 -12 Hz/% RH Humidity Hysteresis +/-1 % RH 0.5 % RH/yr Long term stability Time constant (40 to 95% RH, 2m/s, 63 %) 10 s Relative Humidity Accuracy of HTF 3000LF PVH-3.3 23C Chart 2 SENSOR SOLUTIONS /// HTF3000LF PVH-3.3 9/2015 Page 2
