LL FILIMMFEEL measurement | SPECIALTIES ee @ e TEMPERATURE AND HUMIDITY MODULE HTF3000 Based on the rugged HS1101LF humidity sensor, HTF3000 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 module's linear frequency output. MAIN FEATURES One of the smallest humidity / temperature modules on the market. Stable, proportional frequency output from 0 to 100% RH. Calibrated within +/- 3% RH @ 55% RH at 5.00 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.
