Suggestions please.
Taking a driveway PIR xmtr to modify for other purposes with no actual internal mods.
Thinking of using some emitter taped to the PIR window to activate the xmtr.
Something as simple as a blinking LED to keep the xmtr transmitting while the LED is blinking.
Using one of these. 4VWIN Wireless Home Security Driveway Alarm
or Harbor Freight Home Security Driveway Alarm
Suggestions please. Switch State Open - LED off and no PIR activation Closed - LED blinks to maintain PIR activation.
Option 1: blinking LED and switch and battery.
Option 2: 555 timer, LED, switch and battery.
Or ???
What is needed to activate the PIR. LED color or type ?
Receiver will just be the reeiver's flashing LED with the audio function disabled. I think it is a transducer that I can either smother or cut out of the circuit if it is not part of the receiver function.
What do you think?
