1. Using the NTC thermistor sensor, good sensitivity
2. The output signal of the comparator clean wave is good, the driving ability, only 15mA.
3. Adjust the distribution temperature low detection threshold
4. Operating voltage 3.3 V-5 V
5. The output format: Digital switching output (0 and 1)
6. With bolt holes for easy installation
7. A small size
printed circuit board: 3.2cmx1.4cm 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. By setting the potentiometer, can change the detection threshold temperature (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, NE output is HIGH level falls below the set temperature value, the output is high, the green light does not shine;
3. NE output can be directly connected with the microcontroller by the microcontroller to detect high and low, so as to detect changes in the ambient temperature;
4. MAKE OUR EXITS can directly drive 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 for heating and others;
5. The detection zone of the temperature module 20-80 ° C;
6. This module can also be replaced with a temperature sensor wire for water temperature, water tank controlled.
