{"title":"DFRobot Ultra-Compact ToF Laser Ranging Sensor - 7.8m","handle":"ultra-compact-tof-laser-ranging-sensor-7-8m-1-gram","url":"/products/ultra-compact-tof-laser-ranging-sensor-7-8m-1-gram","description":"This ultra-compact dToF laser ranging sensor uses 940nm laser pulses to measure distance up to 7.8 metres with typical ±4cm accuracy. It is designed for precise, real-time ranging in compact robotics, drone, IoT and automation projects.The module supports UART, I2C and IO communication, making it suitable for use with Raspberry Pi, Arduino and ESP32 platforms. Its narrow 2–3° field of view and 50Hz refresh rate help provide fast, stable readings for obstacle avoidance, navigation, object counting and level detection.With dimensions of just 19.0×12.0×10.3mm and a sensor weight of 1g, it can fit into space- and payload-sensitive builds such as micro-drones, wearable devices or robotic joints. The package includes 1× ToF laser ranging sensor-7.8m and 2× wiring leads.Note: The included cable colours are unusual: RED->GND, Black->VCC. Carefully check the power connections before use.Features:dToF laser ranging: Uses Direct Time of Flight technology with 940nm laser pulses.Long-range measurement: Measures up to 7.8 metres.High-speed updates: 50Hz refresh rate for real-time distance data.Anti-interference performance: Operates under 100,000 lux ambient light.Narrow field of view: 2–3° field of view helps reduce background interference.Multi-protocol support: Compatible with UART, I2C and IO interfaces.Compact and lightweight: 19.0×12.0×10.3mm module with 1g sensor weight.Specifications:Ranging Range: 0.02–7.8mAccuracy: ±4cm (typical)Refresh Rate: 50HzAmbient Light Resistance: 100,000 luxField of View: 2–3°Power Supply: 4.3–5.2V DCCommunication Interfaces: UART/I2C/IODimensions: 19.0×12.0×10.3mmSensor Weight: 1gUseful applications include drone navigation, robot path planning, smart traffic monitoring, parking status detection, material level detection and production line object counting.","vendor":"DFRobot","product_type":"Distance Sensor","in_stock":true,"options":[],"variants":[{"id":15960,"title":"Default Title","sku":"DF-SEN0646","mpn":"SEN0646","price":36.4,"on_sale":false,"in_stock":true,"available_quantity":210}]}
