This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has excellent reliability and long term stability. Please note that this sensor will not work for temperatures below 0 degree.  

Features :

• Relative Humidity and temperature measurement 
• Full range temperature compensation Calibrated 
• Digital signal Long term stability 
• Long transmission distance 
• Low power consumption
