Module instructions
1. Thermistor module is very sensitive to ambient temperature, which is generally used to detect the temperature of the surrounding environment;
2. By adjusting the potentiometer, the threshold value of temperature detection (i.e. control temperature value) can be changed. If it is necessary to control the ambient temperature to 50 degrees, the module will adjust the corresponding ambient temperature to its green light, do will output a high level, and when it is lower than the set temperature value, it will output a high level and the green light will not be on;
3. The do output can be directly connected with the single chip microcomputer to detect the high and low levels, so as to detect the temperature change of the environment;
4. The do output can directly drive the relay module of our store, which can form a temperature control switch to control the working temperature of relevant equipment, or it can be connected to a fan for heat dissipation, etc;
5. The temperature detection range of this module is 20-80 ℃;
6. This module can also be replaced with wired temperature sensor for the control of water temperature, water tank, etc.
