TEMPERATURE AND HUMIDITY MODULE
1
HTF3000LF
RoHS Compliant
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 module’s linear frequency output.
MAIN FEATURES
Ö One of the smallest humidity / temperature modules on the market.
Ö Compliant with RoHS regulation and most of Lead Free Soldering Process
Ö Stable, proportional frequency output from 0 to 100% RH.
Ö Calibrated within +/- 3% RH @ 55% RH at 3.30 VDC.
Ö High quality thermistor.
Ö Stable characteristics with temperature.
Ö High reliability and long term stability.
HUMIDITY SENSOR SPECIFIC FEATURES
Ö Instantaneous de-saturation after long periods in saturation phase.
Ö Fast response time.
Ö High resistance to chemicals.
Ö Not affected by water immersion.
Ö Part could be washed with distilled water.
Ö Patented solid polymer structure.
TEMPERATURE SENSOR SPECIFIC FEATURES
Ö 10 kΩ+/- 1% NTC temperature sensor
Ö Stable
Ö High sensitivity
