Product Specification

Temperature and humidity sensor module HTF3223

Description
Based on the rugged HS1101LF humidity sensor, HTF3223LF is a dedicated humidity and temperature transducer designed for OEM applications where a reliable and accurate measurement is needed. It features a miniature connector for easy, cost-effective mechanical mounting. Direct interface with a micro-controller is made possible with the module’s linear frequency output. 

MAIN FEATURES
• Size and connector type match existing humidity modules.
• Stable, linear proportional frequency output from 10 to 95% RH.
• Calibrated within +/- 5% RH @ 55% RH.
• Optional 10 K +/- 3% NTC temperature sensor (HTF 3223)
• 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.
• Patented solid polymer structure.

TEMPERATURE SENSOR SPECIFIC FEATURES
• High quality thermistor
• Stable
• High sensitivity
