This is a ranging sensor based on TOF (time of flight) technology. With built-in controller and ranging algorithm, the ranging range can reach 15m, the accuracy can reach 2%, and the resolution can reach 1mm. It supports UART and 12C communication, has ultra-small FOV angle, makes the distance longer, has stronger anti-interference ability, and is applicable to both indoor and outdoor environments. It can be used as a ranging tool for distance detection, as a robot obstacle avoidance / route planning, and can also be used in UAV height determination / ceiling detection and other fields Support UART or 12C interface communication. In UART mode, support active query output. In 12C mode, support up to 8 devices in parallel Obstacle avoidance detection and measurement of UAV fixed height robot in application scenario Typical ranging range: 0.10~15.0m Typical ranging accuracy: 0.10-2m2cm; 2-15m2% Measurement resolution: 1mm Wavelength: 750~830nm The complies with Class2 specified in the third edition of IEC 60825-1:2014 Standard Field of View (FOV): 1degrees -2degrees Communication Interface: UART (TTL signal line level 3.3V) 12C (supports multiple parallel connections, the slave address is 0x08+module ID) Communication baud rate: UART: 115.2Kbps-3000Kbps (default 921.6Kbps) I2C: up to 400Kbps Number of cascades: up to 8 can be connected in parallel via I2C Power supply voltage: 3.7~5.2V (anti-reverse connection protection) Product power consumption: 610mW (UART active output, power supply voltage 5.0V, current 122mA) Working temperature: -10Celsius~60Celsius Colour:black Material: ABS Package Contents: 1 x TOF Range Sensor (B) Sensor 1 x GH1. 25 4Pin Connecting Cable 1 x GH1. 25 4Pin To Custom Cable Only the above package content, other products are not included.
