How does a simple, cheap sensor light know how long to stay on?

I installed a cheap motion sensor LED light in our fridge and wondered how it was “programmed” to stay on for one minute after sensing motion and whether this time could be changed when it only has a motion switch and on/off switch.

In: Technology

Simple ‘programs’, especially those involving only a handfull of logical parameters (if, and, not, or) are buildable straight into a circuitboard. Timers are also implemented like this.

So no you wont be able to alter it, since its the patterns of conductivity and components built into the little board in the light that carry the instructions.

In theory you could learn some electronics and accomplish this with a soldering iron
