Project Overview
This Automatic Garage Door Management system is based on following components:
- Blue Gecko Board
- HC-SR04 Ultrasonic Sensor
- Stepper Motor
- Bluetooth Low Energy
In a nutshell, This system simply takes the values of the distance of an object (car) and then decides whether to open the garage door based on the position of the car relative to the garage door. Ultrasonic sensor can measure values from 2cm to 400cm, which is sufficient enough for the application of a garage door. The system uses Bluetooth Low Energy (BLE or Bluetooth smart) to communicate with the user via a mobile phone app EFR Connect. The user will connect to the Gecko board (which will act as a server) through the EFR Connect app (which will act as a client) using an encrypted link. Only after the connection is established AND the client has turned on indications, the gecko board shall start taking measurements for the distance and then open the door if the car is too close to the door.
Using the code of Assignment 8 as a starting point, this project was developed to send values to the user using Bluetooth Low Energy.
