ABSTRACT
Precise characterization of parameters that influence thermal resistance of buildings is owe to the use of accurate instruments. AM2302/DHT22 is a great performance ambient sensor, ensuring high reliability and excellent stability in terms of measuring temperature and humidity. This article deals with assessing accuracy of the aforementioned low-cost sensor using the obtained measurement through 4 sensors in a SELECTA oven. Statistical calculations show that the sensor is more accurate in terms of measuring temperature rather than humidity one since discrepancy of the temperature parameter is less than the humidity one. The maximum range of standard deviation derived for temperature and humidity parameters are less than 0.13 and 1.33 respectively.
