Motion sensor

A motion sensor is a device that detects physical movement in a certain area. It senses movement by using technologies like infrared light (PIR sensors), microwave radiation, ultrasonic waves, or even cameras. When the sensor detects motion, it usually triggers an action, like turning on a light, sounding an alarm, or sending a notification.

Uses of motion sensors include:

Security systems: Detect intruders and trigger alarms or security cameras.

Automatic lighting: Turn lights on or off when someone enters or leaves a room.

Smart homes: Automate tasks like adjusting the thermostat, locking doors, or sending alerts.

Industrial automation: Monitor machinery or track products on a production line.

Healthcare: Track patient movements in hospitals or elderly care centers.

Energy saving: Reduce power usage by activating devices only when needed.

Gaming and VR: Detect players’ movements for a more interactive experience.
