- Working voltage: 3.3V-5V; Output form: digital switch output (0 and 1)
- Using NTC thermistor sensor, good sensitivity.
- Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.
- Use wide voltage LM393 comparator. With fixed bolt holes for easy installation.
- Use: temperature detection, temperature control sensor, ambient temperature detection.
1. The thermistor module is very sensitive to the ambient temperature, and is generally used to detect the temperature of the surrounding environment;
2. By adjusting the potentiometer, the temperature detection threshold (ie, control temperature value) can be changed. If the ambient temperature needs to be controlled at 50 degrees, the module will adjust its green light to the corresponding ambient temperature, and DO will output high power. Level, below this set temperature value, output high level, the green light does not light;
3. The DO output terminal can be directly connected to the single chip microcomputer, and the high and low levels are detected by the single chip microcomputer, thereby detecting the temperature change of the environment;
4. The DO output terminal can directly drive the relay module of our shop, which can form a temperature control switch to control the working temperature of related equipment, and can also be connected to a fan for heat dissipation, etc.;
5. The temperature detection range of this module is 20-80 degrees Celsius;
6. This module can also be replaced with a temperature sensor with a wire for the control of water temperature, water tank, etc.
