The ToF Laser Ranging Sensor leverages dToF (Direct Time of Flight) technology with 940nm laser pulses to deliver precise distance measurements up to 7.8 meters (±4cm accuracy), even in high-interference environments (ambient light resistance: 100,000 lux). Compatible with Raspberry Pi, Arduino, and ESP32 via UART/I2C interfaces, its ultra-compact design (19×12×10.3mm, 1 gram) and multi-protocol support make it ideal for robot and drone obstacle avoidance and navigation, robotics, IoT, and industrial automation.
Ultra-Lightweight & Miniaturized Design
Weighing 1g with dimensions of 19×12×10.3mm, the sensor is one of the smallest and lightest dToF solutions on the market. Its 19mm³ footprint allows direct integration into micro-drones, wearable devices, or robotic joints without compromising payload capacity or mobility. The design eliminates traditional bulky optics, enabling deployment in space-critical applications like micro-drone obstacle avoidance or smartwatch gesture control.
High-Speed Dynamic Ranging
With a 50Hz refresh rate, the sensor delivers real-time distance updates, critical for applications requiring rapid response, such as drone obstacle avoidance or industrial conveyor belt monitoring. The narrow 2-3° field of view minimizes interference from ambient light and background noise, ensuring stable performance in both indoor and outdoor settings.
Robust Anti-Interference Capability
The sensor operates reliably under 100,000 lux ambient light (equivalent to direct sunlight), making it suitable for outdoor traffic monitoring or construction sites. Advanced algorithms filter out environmental noise, enabling consistent accuracy in dynamic scenarios like vehicle speed detection or material level measurement.
Applications
Drone Navigation: Real-time altitude hold and obstacle avoidance in confined indoor spaces.
Robotics: Dynamic path planning for AGVs (Automated Guided Vehicles) or service robots.
Smart Traffic Systems: Vehicle flow monitoring and parking status detection.
Industrial Automation: Material level detection and production line object counting.
