PIR timer override

[JohnsonsAces]

As always, I'm a level 2 student so please ignore the ignorance.

Is it possible, and if so how, to wire up a PIR with a switch that has the ability to turn the light off after the PIR has been activated. Or in all cases do you have to wait for the timer to expire?

Side question - are there any other applications for a PIR? Are they used for anything other than switching on lights?

Thanks in advance

do want the override the pir ?

you can override a pir, either forcing it on or forcing it off.

why don't you have a go at drawing a diagram of how you might wire it so you can force the light on when the pir is off

then try to change the drawing so that you can force the light off when the pir is on

finally you can combine the drawings and come up with a circuit that allows the light to be switched on-off-auto using a 3 way switch.

p.s pir detectors are often used for intruder alarms, sounders, beacons and sometimes gates.

I like Matt and his vids but definitely found JW easier to follow on this.
