Ultra-Compact ToF Laser Ranging Sensor (7.8m)

SKU: SEN0646

The TOF Laser Ranging Sensor (TOF-7.8) is a dTOF-based device. It has <2cm blind area, max 7.8m range (env reflectivity-dependent), ±4cm typical accuracy, 100K LUX light resistance, and supports UART/I2C/I/O. TOF-7.8 highlights ultra-small size (1g) & cost-effectiveness, ideal for consumer electronics, robots, drones, and easy to embed in space-constrained devices.

    This article offers comprehensive instructions on how to set up Arduino for serial active output, including hardware and software preparation, wiring diagrams, and sample code for TOF sensors, focusing on efficient communication and parameter configuration.

    2. Example Code for Arduino-Serial Query Output

    This article offers a comprehensive guide on executing serial query output using Arduino, featuring hardware and software preparations, wiring diagrams, and sample code to effectively use TOF sensors with ESP32 development boards.

    3. Example Code for Arduino-IIC Output

    IIC mode can be used in single module and cascade. In IIC communication mode, the controller sends a read frame to the expected query module with the specified slave address according to the IIC communication timing, and can obtain the distance and other related information of the module. In addition, you can also change the module's output mode and other parameters through IIC communication. The read frame and write frame formats follow the NLink_TOFSense_IIC_Frame0 protocol.
