Details
The TOF Laser Range Sensor is a TOF-based (time of flight) laser ranging sensor with embedded MCU and ranging algorithm, which is capable of offering up to 5m measuring range, ±1.5cm accuracy, and 1mm resolution. It supports cascade ranging via UART or CAN bus, configurable data output including active output and query output.
This sensor can be widely used in applications like common distance measuring, robot obstacle avoidance / route planning, as well as drone altitude setting / ceiling detection, and more...

Configurable communication bus, providing two ports (identical electric connection) for cascade ranging
active output / query output
Configurable data output mode, make it more flexible to acquire data
Multiple sensors can connected in series thanks to onboard two identical ports, and each sensor can be configured with an ID,
therefore, the ranging data of all sensors can be acquired through one single communication bus.
When using cascade ranging, three output modes are available: UART query, CAN query, and CAN active output
up to 8x cascades on UART bus, up to 7x cascades on CAN bus
provides host computer assistant software, offering functions including sensor configuration, wave form monitor, data analysis, data record export and replay, firmware upgrade, and so on.
