LM393 3.5-28V Voltage Comparator Module

LM393 3.5-28V Voltage Comparator Module Adjustable Precision Signal Waveform Shaping High-Level Dual Output Led Indication

By adjusting the reference voltage adjustment potentiometer to generate the reference voltage, the Sensor and pressure resistance of the voltage are compared with a reference voltage, high and low levels of comparison results output.

The threshold valid range is 0 – (supply voltage minus 1v). For example, for a 5v power supply, the reference threshold voltage effective value is 0-4v, which can achieve a comparison output. If the threshold voltage is greater than 4v with a 5v supply, the output will remain low for a period equal to no output
