Use this FORM C PIR for all of your training builds.
Easy to add a 9V and connect to your output. You can add in your safeties and other switches for easy reset.
If you'd prefer we create your trainer so you have it to use straight out of the box, let us know and we'll work up a quote for you.
We've been using this PIR extensively for years by adding it to a small project box with an external power and arm switches.
