TOF Sense Laser Range Sensor (5m)

SKU: SEN0337

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.
