LM393 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, Sensor and pressure resistance of the voltage compared with a reference voltage, high and low levels of comparison results output.

Threshold voltage valid range 0 – (supply voltage minus 1V). For example, a 5V power supply, the reference threshold voltage effective value is 0-4V, can achieve 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

  • Power supply voltage: DC 4.5-28V
