Abstract
In a method for controlling the temperature inside an environmental chamber using an electronic device, a target temperature T0, and a current internal temperature T and a current humidity level RH inside the environmental chamber are acquired. A current dew point Td of air inside the environmental chamber is calculated using a dew point calculation formula requiring the current internal temperature T and the current humidity level RH. The surface temperature of an object under test which is placed in the environmental chamber is detected using a temperature sensor. The environmental chamber is controlled according to the target temperature T0, the current internal temperature T, the current humidity level RH, and the surface temperature of the object under test.
