LM393 Voltage Comparator Comparator Module
Voltage comparator module with integrated LM393 comparator. Compares voltage values from positive and negative inputs. If the voltage from the positive input is greater, it gives an output equal to the positive supply voltage. If the voltage from the negative input is greater, our output will be equal to the negative supply voltage. It has a voltage value between 4.5-28v.
Features:
- Input Voltage: 4.5-28V
- Comparator Chip: LM393
- Size: 45*17mm
- Application: for NTC thermosensitive temperature sensor, photosensitive sensor
- Using method: setting reference voltage to create reference voltage With potentiometer, compare the voltage produced by the sensor and split resistor with the reference voltage, get high / low level comparison result output
