- Actively monitors the tire pressure and alerts the user through an app if low pressure is detected.
- The Smart Trailer will check if all the lights on the trailer are working properly.
System
Methods
- How was the problem solved?
- Bluetooth Tire Pressure Sensors.
- Variable Voltage Regulators connected to the RPI’s GPIO pins receive the light data.
- SQL Database actively updates with new information received from the sensors.
- A web server hosts the data in a JSON format for the mobile application to read.
- Mobile phone application actively checks for updates and displays current information.
- Bluetooth Sensors: Python script to read Bluetooth data and decode into PSI.
- Light Data: Using a Python script, GPIO pins are monitored for changes.
- Mobile Application: Built with React Native to allow simultaneous iOS and Android development.
