Feature

●The LM393 universal single supply comparator module allows linear tunability with precise voltage. It can achieve a high and low level as well as a load-controlled dual channel output. It is convenient for front-end detection and detection of single chip switching. Apply the NTC heat sensitive temperature sensor, light sensitive sensor and vibration sensor.
●Hole diameter: approx. 3.2 mm
●Input voltage: 4.5 - 28 V
●Method of use: create reference voltage by potentiometer to adjust the reference voltage. Compare the voltage generated by the sensor and divide the resistance with the reference voltage. Achieve a comparison result output at and low level.
●Comparator chip: LM393
