Hello All,
I am working on a project here and need some help. Here is what I am looking to do. Right now it currently stands at - a voice activated system is used to setup off traps. The person at the stand yells "Pull" into the speaker and the machine releases a target. The speaker is so sensitive, that even a clap sets off the machines. I thinking about using a PIR sensor. The PIR sensor would be set up so when the gun is raised in front of the PIR sensor, the PIR sensor turns "ON", which then put the speaker in ready mode, the shooter would then yell "Pull", the machine throws target. Then it would it repeat itself. The shooter would then go through the same follow through - raise the gun pass the PIR sensor, the sensor turns ON, which then activates the speaker, the shooter then yells "Pull" and so on. This would eliminate target being falsely thrown. The voice activated circuit uses LM324 chip. The PIR output is 3v. I am not sure if I need to go directly to the LM324 chip to tie in the PIR sensor to, or splice the PIR sensor to cable that runs from the speaker to the voice activated circuit. Would I a need a relay so when the PIR sensor is ON, the relay will close, put the speaker in ready mode and wait for the command then turn off until the sensor is triggered again. The voice activated circuit uses 15vdc as input power. The speaker is using the LM324 chip and uses 12vdc at pin 4 & pin 11. The PIR sensor uses 12vdc to power it, but outputs 3v at the out pin.
Thank you in advance.
