1 / 5 page TECHNICAL DATA RELATIVE HUMIDITY/ TEMPERATURE MODULE HTM2500 1 Based on the rugged HTS2010 humidity / temperature sensor , HTM2500 is a dedicated humidity and temperature transducer designed for OEM applications where a reliable and accurate measurement is needed. Direct interface with a micro-controller is made possible with the module’s humidity linear voltage output. MAIN FEATURES q Small size q Not affected by water immersion q Full interchangeability q High reliability and long term stability q Typical 1 to 4 Volt DC output for 0 to 100% RH at 5 V DC supply q Humidity calibrated within +/- 2% RH @ 55% RH q Temperature measurement through NTC 10kohm +/- 3% direct output q Ratiometric to voltage supply q Suitable for 3 to 10 Volts supply voltage HUMIDITY SENSOR SPECIFIC FEATURES q Instantaneous de-saturation after long periods in saturation phase. q Patented solid polymer structure. q High resistance to chemicals. q Fast response time. MAXIMUM RATINGS Peak conditions: less than 10% of the operational time.
