Frequently asked questions
Which sensor does it work with?
It is designed for a pyroelectric (PIR) sensor and needs external passive components arranged as shown in the datasheet application circuit.
What is the difference between the two operating modes?
In retriggerable mode, new motion detected while the output is active restarts the output timer. In non-retriggerable mode, it does not restart the timer.
