5m TOF Sense Laser Range Sensor

The TOF Sense (SEN0337, printed Nooploop) measures distances from 1 cm to 5 m with a laser using the time of flight principle. Resolution 1 mm, error up to ±1.5 cm, 10 measurements per second. It communicates via UART or CAN and has two identical connectors: with adjustable IDs, up to 8 sensors (UART) or 7 (CAN) can be cascaded and read via one connector.

Features:

• Measuring range selectable: short, medium or long
• Field of view (FOV) adjustable from 15° to 27°
• Two identical connectors, the power supply is connected at all connectors, each one can supply the sensor
• UART with 3.3 V level, 921600 baud by default; CAN 1 Mbit/s by default
• According to DFRobot, the red and black wires are swapped on older units, check before the first connection
• Button on the board for restart
• Laser 940 nm, class 1

Application Examples:

• Distance measurement
• Obstacle avoidance for robots
• Altitude hold and route planning for drones
• Several measuring points on one bus
