I am building a sensitive intruder alarm PCB using Proteus 8.6 as shown in this circuit I cant find some of the circuit components on Proteus. I need help in the names I should search for ?
The red encircled components are
- IR LED
- photo diode
- regular resistor. You're apparently confused by the LED symbol left of it.
The IR LED and photo diode are forming a light barrier. Don't think that there's a specific method to model it in Proteus, generally variable illumination of the photo diode. Did you notice that the simulation in the link replaced it by a push button?
