Project Idea

For my final in ECE 387 Embedded Systems Design, I set out to improve the motion detection system from my midterm project. My goals were to add wireless functionality so the pir sensor could alert an alarm that is 10 feet away. I implemented a 433MHz wireless transmitter and receiver with the sensor to achieve this.

Summary of Results

Overall, the project was successful. The transmitter arduino detects motion using the PIR Motion Detector. When this happens a timer starts and counts how long motion is detected. Based on this time a message is sent to the receiving arduino. This arduino reads the message and enters a state based on the message. The states set off different leds and a buzzer. All of my goals for the project were achieved. It is a cool tech demo but in reality will not do much to deter criminals. If a louder speaker or a floodlight were implemented, this could be a practical security system.
