Years ago, I was late to a movie that a group of friends had invited me to go see. There were no parking spots outside of the theater and I was forced to park in the parking deck. When I pulled into the spot, I couldn't tell how close I was to the wall in front of me. There was a phantom distance between the front of my car and the end of the parking space and I wasn't sure how much room was left. Just before moving my car a few more inches into the spot I decided I would get out and check to see how much farther I could go. That's when I discovered I was less than an inch away from the wall. The damage would not have been severe however, I began thinking how often people like me have to park in a parking garage and are not always sure how close they truly are to the wall. That is what the IoT is intending to solve. This circuit is designed to have one part attached to the front of your car and the other part to be connected inside. The sensor on the front will transmit a wireless signal to the photon next to the driver's seat when the HR-SRO4 device gets within a selected distance. This will ensure that the car is not close enough to make contact with the wall however, it is far enough into the parking spot so that your vehicle will not be in danger of being hit by other passing cars. This gives a measure of safety to parking in tight places and gets rid of the phantom distance that we all dread.
IFTTT is the program that we used to receive the events being sent from the main photon. This site allows the data to be recorded and posted in a google sheets page. This allows the information sent form the particle code to show up in real time in the program. It will update each time the sensor in the circuit is triggered and the LED lights up. Below is a live link of the amount of times the sensor is set off and recorded in the console. These data points can be erased each time you finish parking and get out of the car. The google sheets document is connected directly to the main photon so that each time the sensor gets close to the wall, another row of data will appear in the document. This will automatically be recorded on the graph as an event which will increase the bar graph.
