Hi,
I want to test PIR motion sensor by without making any human movement. Which means i want to test PIR motion sensor by using software and testing circuits. Because i want to test hundreds of motion sensor, so i can't check each sensor by making human movement.
Please help me.

Thanks
 

If you want to do a production test for senstitivity a variable IR-source at a fixed distance could help. However to simulation a physical motion you either have to move the target, or the sensor. There are special test maschine needed to test physical values with magnetic or optical sensors in volume production.

Enjoy your design work!
 

The "IR-source" must be far IR, e.g. an open filament or any electrical heater with small time constant. For a basic functional test, it must not neccessarily be moved, just switched.
