Module for use
1. The thermal resistance of the module is very sensitive to the ambient temperature, typically for detecting the temperature of the surrounding environment ;
2. Through the potentiometer adjustment, you can change the temperature detection threshold ( ie, control temperature ), such as the need to control the ambient temperature is 50 degrees, the module in the corresponding ambient temperature to its green light , DO high power output when flat, set the temperature below this value, the output is high , the green light does not shine ;
3. DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting temperature changes in the environment ;
4. DO output of the relay module can directly drive the shop, which can be composed of a thermostat to control the temperature of work-related equipment can also be connected to the cooling fan, etc. ;
5. The temperature detection range of the modules 20 to 80 ° C ;
6. The module can be replaced with a line of temperature sensors used to control the water temperature, water and the like.
