Many older cars lack proximity sensors that let the user know how close their car is to various obstacles, whether it be their garages, parking spot walls, or even curbs. Though this can be handled through various tricks of knowing where to look in the rearview or side mirrors to know where the front, sides, or back of the car is with respect to walls and other obstacles, it is always better to be sure. We aim to solve this inconvenience that comes with older model cars. # Solution Describe your design at a high-level, how it solves the problem, and introduce the subsystems of your project. Our solution involves using 4 proximity sensors that can be placed on each corner of the car, with a receiver that can be placed inside the car. These will be linked through bluetooth and the receiver itself will also contain 4 lights on each of its corners. This will correspond with each sensor placed, and light up as well as produce an auditory cue (most likely small “beeps”) to alert the user how close they are to an obstacle and where it is. The closer you are to an obstacle, the faster the frequency of the beeps. # Solution Components ## Subsystem 1: Proximity Sensor The first, and main system, will be the sensors placed all around the car. Each module will be the same, regardless of where on the car it is placed. Each module will consist of 1-3 ultrasonic sensors(HC-SR04) based on their predicted placement on the vehicle, our custom PCB, a small watch battery, and a wireless RF transceiver (WRL-10534). The module will constantly transmit distance data to the receiver module located within the vehicle to make sure the driver is aware of how close they may be to any potential obstacles. ## Subsystem 2: Receiver The receiver subsystem will be located within the vehicle, consisting of an RF receiver (WRL-10534) to communicate with the above proximity sensors, a power adapter to get power from the USB/car power, and a microcontroller(ATmega328P) to read input from proximity sensors, and output signals to control the lights and speakers over bluetooth using a bluetooth module (CC2541F256TRHATQ1) if necessary and if the vehicle is too close to an object. ## Subsystem 3: Lights + Speaker The light and speaker system will consist of a small speaker that we have that will change frequency based on how close an object is, combined with a set of red LED diodes to represent which sensor is being triggered so the driver knows which direction to avoid. # Criterion For Success Our criterion for success will be testing with an actual car, where we reach a constant beep when we reach a distance of less than one foot to an obstacle, which will be our reassurance that the sensors work. Our second criterion for success is to get someone to use the system and determine if they are able to stop before/avoid obstacles with a relatively safe margin of error. |
