Voltage Comparator Module Adjustable Precision Signal Waveform Shaping High Level Dual Output Led Indication, LM393
Module Input Voltage: 4.5-28V
Module Size: Length 39.5mm Width 17mm
Comparator Chip: LM393 Comparator Chip
Application: for NTC thermosensitive temperature sensor, photosensitive sensor.
Usage Method: by reference voltage adjusting potentiometer to generate reference voltage, and compare voltage generated by sensor and divide resistor with reference voltage, achieving high/low level comparison result output.
Module Sensors can be connected to many sensors such as:
Resistive Sensor
NTC Thermal Electronic Resistance Temperature Sensor
Photosensitive Electronic Resistance Photosensor
Vibration Sensor, Etc.
Note:
Effective Range of Threshold Voltage 0- (Power Supply Voltage minus 1V).
Compared with 5V Power Supply, the effective value of reference threshold voltage Is 0-4V, which can realize comparative output. If the threshold voltage Is greater than 4V under the condition of 5V Power Supply, then the output will remain Low and equal to No Output.
