I am building test rigs and need to trigger motion detectors remotely. I would also like to avoid using a light source. The devices I've encountered all use an Excelitas 968 pyroelectric sensor (http://www.excelitas.com/downloads/LHi%20968%20PYD%201398%20-%20High-End%20Pyro.pdf); I'd like to remove it and use simulate its signal instead. But I've struggled to find out what I'd need to do, right down to what signal the sensor itself produces.
How can I simulate this pyroelectric sensor?
