Here is a description of how it generally works:
- Components: A wireless mouse contains several key components, including an optical or laser sensor to track movement, a microcontroller to process data, a wireless transmitter (RF module), and a power source (battery).
- Movement Tracking: When the mouse moves, the sensor tracks the surface movement using reflected light. The microcontroller then processes this movement data and encodes it for transmission.
- Signal Transmission: The built-in transmitter sends an electromagnetic (radio) signal containing the movement and click information to a receiver connected to the computer, often via a USB port.
- Signal Reception and Action: The receiver accepts the signal, decodes it, and passes the information to the computer’s operating system, which translates it into cursor movements and actions on the screen.
- Connectivity: Most modern wireless mice use a dedicated USB dongle for a stable 2.4GHz RF connection or connect directly via Bluetooth.
