Description

Features:
Input voltage: 4.5-28V
Comparison chip: LM393 comparator chip
Module sensor can connect many sensors, such as: resistive sensor: NTC thermistor type temperature sensor, photoresistor type light-sensitive sensor, vibration sensor, etc.
Size:39.6*18mm
Weight: 3.6g

Application:
Adjust the reference voltage to adjust the potentiometer to generate the reference voltage. The voltage generated by the sensor and the voltage splitter is compared to the reference voltage to achieve the output power of the high and low comparison results.

Note:
The effective range of the threshold voltage is 0- (supply voltage minus 1V). For example, 5V power supply, the effective value of the reference threshold voltage is 0-4V, and the comparison output can be realized.
If the threshold voltage at 5V power supply is greater than 4V, then the output will always remain at a low level the same without output.
