Introduction 
The thermal resistance of the module is very sensitive to the ambient temperature , typically for detecting the temperature of the surrounding environment.
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 ,
Temperature measurement range: -55°C / +125°C This module includes a NTC Thermistor – its resistance falls with higher temperature.Digital Out: While measuring a temperature which is higher than the limit value, it will be shown here – you can set the limit value via potentiometerAnalog Out: Direct measurement of the sensor unitLED1: Shows that the sensor is receiving powerLED2: Shows that a magnetic field was detected
