FEATURES

• Using the NTC thermistor sensor , good sensitivity.
• The comparator output signal is clean, good waveform , driving ability , more than 15mA.
• Adjust the temperature distribution position detection threshold.
• The working voltage: DC 3.3V-5V.
• The output format : digital switching outputs ( 0 and 1 )
• A fixed bolt holes for easy installation.
• Using a wide voltage LM393 comparator.

HOW TO USE:

• 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 , DO high power output when flat , set the temperature below this value, the output is high , the green light does not shine ;
• DO output can be directly connected to the microcontroller through the microcontroller to detect high and low , thereby detecting temperature changes in the environment.
• 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. .
• The temperature detection range of the modules 20 °c to 80 °c.
• The module can be replaced with a line of temperature sensors used to control the water temperature , water and the like.
