Temperature detection, temperature control sensors, ambient temperature detection.
- Using the NTC thermistor sensor , good sensitivity
- The comparator output signal clean waveform is good , driving ability, than 15mA
- Adjust the temperature distribution bit detection threshold
- Working voltage 3.3V-5V
- The output format: Digital switching output (0 and 1)
- With bolt holes for easy installation
- Using a wide voltage LM393 comparator
Module for use：
- The thermal resistance of the module is very sensitive to the ambient temperature , generally used to detect the ambient temperature
- 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
- DO output can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting the ambient temperature changes
- 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
- The detection range of the module's temperature 20-80C
- This module can also be replaced with a wire temperature sensor for water temperature, water tank controlled
- Size: 3.2x1.4cm/1.25*0.55"
