Product description
This product is a high accuracy temperature and humidity sensor used in smart home conditions.
It consists of a capacitive sensor element used for measuring relative humidity and a negative temperature coefficient (NTC) thermistor used for measuring temperature.
Every sensor was calibrated in an accurate humidity room. Small dimension, ultra low power consumption and more than 20m's signal transmission distance make it a good selection for various application.
The detecting range of this sensor is 5% RH ~ 99% RH, and -40°C ~ 80°C.
The accuracy of this module can gets up to 0.3 degree in temperature and 2% in relative humidity.
