3pcs Lm393 3.5-24v Volta Comparator Module With Led Indicator

LM393 universal single supply comparator module enables precision voltage linear tunability. It can achieve high and low level and load driven channels output. It is convenient for front-end acquisition and acquisition of single-chip switching. Apply for NTC thermo sensitive temperature sensor, photosensitive sensor and vibration sensor.Using : Generate reference voltage by reference voltage adjusting potentiometer. Compare voltage generated by sensor and divide resistor with reference voltage. Achieving high and low level comparison result output.Input Voltage: 4.5 -28VHole Diameter: app.3.2mm/0.13inComparator Chip: LM393G: Ground/NegativeD: High/Low OutputV: Positive Out: Load PositiveIN: Input Voltage PortColour: greenMaterial: PCBSize: 39.5x17mm/1.56inx0.67inPackage Contents:9 * LM393 Voltage Comparator ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
