A metal detector is a device designed to detect the presence of metal nearby, and it is commonly used for locating metal objects on the surface, underground, or even underwater. In this project, the IndusBoard coin is programmed to function as a compact metal detector by leveraging its built-in magnetometer sensor.
The magnetometer sensor is used to detect changes in the surrounding magnetic fields. When a metal object comes close to the IndusBoard, the magnetometer readings fluctuate due to the disturbance in the magnetic field caused by the metal. These fluctuations are detected and interpreted by the IndusBoard to signal the presence of metal.
Additionally, a display can be connected to the IndusBoard coin, offering versatility in how the device is used. Depending on the programming, the display can serve two main functions:
- Password Entry and Command Execution:
- The display can be programmed to allow the user to enter a password or command. Once the correct password is entered, the IndusBoard can perform specific tasks, such as entering a saved password on another connected device or executing other predefined commands.
- Metal Detection Indication:
- Alternatively, the display can be used to provide visual feedback during metal detection. For example, it could show real-time data or alerts when metal is detected nearby, enhancing the functionality of the metal detector by offering immediate, clear visual indications.
By integrating the magnetometer sensor and display into this project, the IndusBoard coin transforms into a versatile tool that not only detects metal objects but also offers additional features like password management or command execution based on how it is programmed. This makes it a powerful and flexible solution for both metal detection and secure device interaction.
