4. Návod k obsluze
Time-of-Flight (ToF) Measurement Principle
The TOFSense-F2 sensor determines distance by measuring the time it takes for a light pulse to travel from the sensor to an object and back. This principle allows for accurate and reliable distance readings.
Komunikační rozhraní
The sensor supports multiple communication protocols, allowing flexibility for various integration needs:
- Rozhraní UART: For serial communication, connect the sensor's UART_RX and UART_TX pins to the corresponding pins on your microcontroller. Refer to the manufacturer's documentation for specific baud rates and data formats.
- Rozhraní I2C: For I2C communication, connect the sensor's IIC_SDA and IIC_SCL pins to your microcontroller's I2C bus. The default I2C address should be confirmed from the official documentation.
- Rozhraní I / O: The I/O pins can be configured for specific functions as detailed in the sensor's technical datasheet.
