Distance Sensor For Parking

Purpose

This is a safety parking project, consists of developing devices that collaborate to alert drivers when they have reached certain distances from set points. For the example that this project demonstrates, the set point will be a wall, representing the inside of a parking garage.

Setup:

Two Particle Argons were used for successful communication and functionality. One sensor, the buzzer, is located inside the car. The second sensor, an ultrasonic ranger, is mounted on the bumper of the car. The ultrasonic sensor constantly relays distance information to Particle Argon #2, which it is physically connected to. Particle Argon #2 then sends information to the Particle Argon #1, located inside the car, which can activate the buzzer and LED.

Operation:

While the car is 100cm or farther from the wall, the LED confirms this by shining green while the buzzer remains quiet. While the car is within 50 - 100 cm from a wall, the LED interprets this data with orange and the buzzer activates intermittently. While the car is less than 50cm from the wall, the LED shines red and the buzzer is activated continuously, which can be turned off with the button component.

All distances at which the LED changes color may be changed. The ones used are as specified by the written code, which can be downloaded below heading "Code."
