Voltage dividers set the high and low reference. Load is only triggered when the input is IN BETWEEN the high and low window. (input is the DC source with the orange input)
Voltage source between the two op amps / comparators is the input.
Remove inverter to trigger OUTSIDE of high and low ref.
Currently set to trigger between 1/5th and 3/5ths Vcc ( between 1V and 3V ).
This is a very useful circuit as it will let you knoe when certain criterias are met from sensor equipment.
