What happens when the motion or presence detector is activated?
- Lights will turn on for a period.
There are PIR sensors readily available with all the necessary control circuits to switch lamps on, with controls to let you select how long the lamps should be kept on for after the movement stops. Commonly they also have an ambient light sensor and can be configured to stay off when the light is above a specified threshold. You can get light fittings with these PIR sensors and control circuits integrated.
Is there anything stopping you from using these commercial off the shelf units?
