Description

LM393 voltage comparator module adjustable precision signal waveform shaping high level dual output LED indication

Module input voltage: 4.5-28V Module size: length 39.5mm width 17mm Comparator chip: LM393 comparator chip Module sensors can be connected to many sensors For example: Resistance sensor: NTC type thermistor type temperature sensor photosensitive resistor type photosensor vibration sensoretc! Usage: adjust the reference voltage by adjusting the potentiometer with reference voltageand compare the voltage generated by the sensor with the reference voltage generated by divider resistance to realize the comparison result output of high and low levels. Attention: valid range of threshold voltage: 0- (power supply voltage minus 1V). For examplefor 5V power supplythe effective value of the reference threshold voltage is 0-4Vwhich can realize comparative output. If the threshold voltage is greater than 4V under the condition of 5V power supplythe output will remain low and equal to no output.
