Hi ,
I am designing automatic light control based on motion detected by PIR sensor (HCSR 501) ,
I am using Optocoupler and triac based circuit to light up the bulb. Anode of Optocoupler has 330Ω and a led connected to it. The issue is in interfacing with PIR sensor, though i have level shifted output of PIR to 5V using transistors(since optocoupler works on 5V) , it does not glow the bulb.
Any suggestions please?
