64 – LDR Window Device
$39.95 – $89.95
This circuit utilizes a Quad Comparator OP AMP IC as a window comparator to test an LDRs voltage against two reference voltages, one high reference and one low reference.When the Voltage at the zone reads outside the window, the circuit utilizes an N-Channel MOSFET to fire a single detonator.
