does anybody have or could tell me where to get the circuit for PIR sensor,you know,the thing to detect motion.Just as simple as if there is a motion and the light will be turn on.

thanks..

but a ready PIR package is very better than making one i think
bye the way you need for a timer too...

good luck
 
hm thanks for the url. Timer?? if that is for the PIR circuit, its ok, i think i just can add any timer circuit (power on delay or power off delay circuit) to the output of the PIR circuit relay.Thanks for reminding :wink: . i know there is PIR package on the market but i just couldn`t find one,yet.I`ll have a look to the circuit 1st. thanks epilot.

a PIR package has not any really timer in it NORMALLY and when PIR detects someone its relay will be active for only a few secends and you said you want to turn on and off a light by it(only for places that a person does a motion not for setting rooms..)so you need for a timer...

you can find pir packages in the BURGLAR stores

yup,this is what i have in mind.i have a timing circuit that works like this,the timer relay will be de-energize a few sec/min (as I pre-set it) after the last input voltage it recieve (that will be from the motion sensors circuit).so this timer circuit will turn on/off the light.i think it`s ok for the timing device,just need to work with the motion sensors circuit :wink: but anyway i`ll try to find the PIR pakage 1st as it is so much more easier for me though :lol:
 
Have you done a search for "timer" in this forum? There have been many discussed in the past.
 
look at this

I just order this to use with a PIC chip

hi,
Got this from the web some time ago, cant vouch for it working, needs checking out.:)
