Description
A comparator is used to compare two voltages and produce an output based on their relationship. These are often useful when a simple On/Off output is required from a variable voltage (analog) source. This module has an adjustable set-point so the change between OFF and ON can be configured between the input voltage and ground. The board also features an indicator LED which is lit when the output is set On.
Pinout:
- V: Voltage In (4.5-28VDC)
- G: Ground
- IN: Input: Voltage for comparison
- D: Output: Output (Vin when True)
- OUT: Load
