Temperature and humidity sensor

senzorvlhkosti.PNG
The iTriangle - Temperature & Humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and a negative temperature coefficient (NTC) thermistor measures temperature. It has excellent reliability and long term stability. Please note that this sensor will not work for temperatures below zero Celsius.

Features


  • Relative Humidity and temperature measurement
  • Calibrated, full-range temperature compensation
  • Digital signal
  • Long term stability
  • Long transmission distance (>20 m)
  • Low power consumption
