Overview

The project aims to create a motion detection system using a Passive Infrared (PIR) sensor and the VSDsquadron Mini Board. When motion is detected by the PIR sensor, the system activates an LED to indicate the presence of motion.

• Detection : The PIR sensor continuously monitors its surroundings for any movement. When it detects motion, it sends a signal to the VSDsquadron Mini Board.
• Processing : The VSDsquadron Mini Board receives the signal from the PIR sensor and processes it using its onboard microcontroller.
• LED Activation : Upon detecting motion, the microcontroller activates the LED connected to it, illuminating it to indicate the presence of motion.

Components

• PIR Sensor
• VSDSquadron Mini Board
