      6. with bolt holes for easy installation
      7. a small board PCB size : 3.2cm x 1.4cm
      8. using a wide voltage LM393 comparator

Module for use
      

1. the thermal resistance of the module is very sensitive to the ambient temperature , generally used to detect the ambient temperature ;
      

2. through the adjustment of the potentiometer , can change the temperature detection threshold (ie, temperature control value) , if necessary to control the ambient temperature is 50 degrees , the module in the corresponding ambient temperature to which the green light , DO output is HIGH level falls below the set temperature value, the output is high , the green light does not shine ;
      

3. DO output can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting the ambient temperature changes ;
      

4. DO OUR outputs can directly drive the relay module , which can be composed of a thermostat to control the operating temperature of related equipment can also be connected to the fan used to heat and other ;
      

5. the detection range of the module's temperature 20-80 °C ;
      

6. this module can also be replaced with a wire temperature sensor for water temperature, water tank controlled.
