Module usage instructions
1. Thermistor module is very sensitive to environmental temperature, which is generally used to detect the temperature of the surrounding environment.
2. By adjusting the potentiometer, the threshold of temperature detection can be changed (i.e. the control temperature value). If the ambient temperature needs to be controlled at 50 degrees, the module will turn on its green light at the corresponding ambient temperature, while DO will output a low level. When the temperature is lower than the set value, the output will be high and the green light will not turn on.
3. DO output terminal can be directly connected with the single chip computer, through the single chip computer to detect the high and low levels, thereby detecting the temperature changes in the environment;
4. DO output terminal can directly drive the relay module of our store, which can form a temperature control switch to control the working temperature of the relevant equipment, and can also be connected to the fan for heat dissipation, etc.
5. The temperature detection range of this module is 20-80 degrees Celsius.
6. This module can also be replaced by a temperature sensor with wires for water temperature and water tank control.
Connection mode:
1. VCC: Connect the positive pole of the power supply (3-5V)
2. GND: Connecting Negative Electrode of Power Supply
3. DO: TTL Switching Signal Output
