Review on π’ Onyehn IR Pyroelectric Infrared PIR Motion Sensor Detector Modules DC 2.7 to 12V(Pack of 5pcs): Enhance Your Security with Reliable Motion Detection by Kaveen Reyes
Useful. Smart exit.
Right now I'm watching my storage oscilloscope while this thing is plugged in. The output generally appears low and goes high for about 5 seconds when presence is detected. This is very useful as by adding a capacitor you can get either an active low or an active high boost. And that makes it useful for applications where you don't even bother using a microcontroller.
- Everything is fine!
