TEMPERATURE AND HUMIDITY MODULE

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.

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.

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.
