5pcs LM393 Digital Thermal Sensor Temperature Sensor Module for Arduino

Module Features:
1. using the NTC thermistor sensor, good sensitivity
2. the comparator output signal clean waveform is good, driving ability, than 15mA.
3. adjust the temperature distribution bit detection threshold

4. Working voltage 3.3V -5V
5. the output format: Digital switching output (0 and 1)
6. with bolt holes for easy installation
7. a small board PCB size: 3.2 cm x 1.4 cm
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 ^o C;
6. this module can also be replaced with a wire temperature sensor for water temperature, water tank controlled.
