TOF Sense is a TOF-based laser ranging sensor with 1cm-5m range, 1mm resolution, ±1.5cm error, 10Hz update rate, and 15°-27° adjustable FOV. It supports UART/CAN communication (selectable) and active data query. Compact (35.58×12×8.05mm), it fits distance measurement, robot obstacle avoidance, drone altitude/route planning. Its unique feature: dual identical interfaces—cascade up to 8 (UART) or 7 (CAN) sensors, read all data via one interface.

1. Example Code for Arduino-Distance Measurement

Use Arduino UNO R3 (or similar) with TOF Sense Laser Ranging Sensor (5m) to measure distance. With initialization completed, you can get distance value, distance status, and signal strength, which will be displayed in the PC serial tool interface.

Pinout

Please check the wire sequence of the product. The previous wire colors and functions did not comply with electrical specifications, so we have updated the wire sequence once. If you have an older version of the wiring, please swap the positions of the red and black wires yourself. This tutorial is based on the new wiring version.

Color	Name	Description
Red	VCC	+
Black	GND	-
Blue	TTL_RXD/CAN_H	Serial port receive/ CAN bus
Green	TTL_TXD/CAN_L	Serial port send/ CAN bus

Button function: restart
