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 output low 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 tanks , etc.
7.Small plates AO analog output modules can be connected and shop AD by AD conversion, more accurate values ??can be obtained ambient temperature
