3Pcs LM393 3.5-24V Voltage Comparator Module with LED Indicator High Level Output Analog Comparators

LM393 universal single supply comparator module enables precision voltage linear tunability. It can achieve high and low level and load driven dual channels output. It is convenient for front-end acquisition and acquisition of single-chip switching. Apply for sensitive temperature sensor, photosensitive sensor and vibration sensor. Using Method: 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.
