RELATIVE HUMIDITY MODULE HM1500LF Compliant with RoHS recommendations Based on the rugged HS1101LF capacitive humidity sensor, HM1500LF is a dedicated humidity 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 linear voltage output. MAIN FEATURES Small size. Product free from Lead, Cr(6+), Cd and Hg. Not affected by water immersion. Full interchangeability. High reliability and long term stability. Typical 1 to 3.6 Volts DC output for 0 to 100 % RH at 5 V DC supply. Calibrated within +/- 2 % RH @ 55 % RH. Very low temperature dependence. Ratiometric to voltage supply from 4.75Vdc to 5Vdc. Able to operate from 3 to 10 Volts supply voltage HUMIDITY SENSOR SPECIFIC FEATURES Instantaneous de-saturation after long periods in saturation phase. Fast response time. Not affected by water immersion. Part could be washed with distilled water. Patented solid polymer structure.
