Hi..all..
i'm a learner of electronics..so not having good knowledge of electronics..these days i'm trying to make IR gate
as a security gate..so i used this circuit..
At the beginning this circuit is not worked..then i was able to work receiver part..
but i 'm unable to use that oscillator part work..i have changed that values of capacitors as desire..some time i have seen that IR receiver response to the emitter..but it works for few centimeters..Another thing is i put additional ele.capacitor between output and ground of receiver sensor (before that output LED blinks only once i press TV remote)..it worked to me i don't know how it's happen
..that means when i press TV remote in front of IR sensor that output LED of sensor get off..
so i need your guidance to implement this..what i want from you is..
can anybody tell me that
(1) how to make more powerful IR emitter like TV remote so that what IC should i buy for that..
(2)are there any Remote control IC for use for single button(that means single channel) to operate this kind of barrier circuit..
I'm really glad if anyone help me to make this small circuit..
I'm waiting response from you..
Thank you.......
