Looking for a 12V PIR Relay Without a Timer Function
Asked by CraftyCrusader92
I'm trying to set up a basic raccoon deterrent sprayer using a 12V battery, a reservoir with a pump, and spray heads. I purchased a 12V PIR relay, but it has a minimum timing of 1 minute, which is way too long for what I need. I couldn't find any PIR relays on Amazon that offer less than a minute or that don't have a timing function at all. Ideally, I want one that activates immediately and then turns off until triggered again. Does anyone have suggestions for a 12V PIR relay without a timer or one that can operate with a very short delay?
Answers
Since you didn’t provide the specific model of the PIR relay, it's hard to give tailored advice. Many relays operate with a monostable configuration, where you can tweak the timing by changing a capacitor value. If you swap the timing cap out, you might be able to achieve a shorter delay—like 6 seconds instead of 60. I've been through similar projects and can say this sounds like a fun DIY! And honestly, f__k raccoons; they really deserve a good vinegar blast!

You might want to check out using a pulse relay or a one-shot relay, as those can be configured to trigger without a long delay. They could work well for your sprayer setup!
