Module for use
1, thermistor module on the ambient temperature is very sensitive, generally used to detect the temperature of the surrounding environment;
2, through the adjustment of the potentiometer, can be changed to the temperature detection threshold (i.e., temperature control value), such as the need to control the ambient temperature is 50 degrees, the module is then transferred to the green light in the corresponding ambient temperature, DO output high output high level, lower than the set temperature value, the green light is not bright;
DO output of the microcontroller directly connected through the microcontroller to detect high and low, to detect the temperature change of the environment;
DO output terminal can be directly driven shop relay module, which can be composed of a temperature control switch to control the working temperature of the related equipment can also be connected to the fan used to heat dissipation;
5, the module temperature detection range of 20-80 degrees Celsius;
6, the module can also be replaced by a temperature sensor with a line for the control of the water temperature, water tanks, and the like.
