Automatic Light Switches

Basics

• These are a light switch that use a Motion Sensor and often a timer to light a room when people enter, and turn it off after they leave
• The timer is to prevent it from turning off due to a still room (Although this still happens with some models as well as placement locations)
• There is often a manual override switch (on/off) for instantanious off upon leaving or for turning on if broken/experiencing an error
• Could most likely be done without any sort of processor, or be done with a VERY basic arduino
• Basic sound and daylight sensing (Photoresistor + logic, and a VERY lofi mic (Clapping/footsteps and not much else would be registered basically "is ther commotion" )
• Most Likely Uses less power than a IOT Light Switch and more secure, but also less capable, and depending on the timer may be less instant (unless manual off is used upon leaving
• Also has some accesability and convienence benefits perhaps
• Should Decrease Electricity Waste even with neglagent users
