Waveshare TOF MINI Laser Range Sensor
Description
The Waveshare TOF MINI Laser Range Sensor is a compact TOF MINI Range Sensor based on Time-of-Flight technology. It integrates a controller and ranging algorithm to measure up to 0.02m ~ 4m through a simple UART distance sensor interface.
This laser range sensor is designed for indoor distance measurement, robotics obstacle avoidance, ceiling detection, path planning and material level sensing. The TOF MINI Laser Range Sensor offers typical accuracy of +/- (1% ~ 3%), a 30Hz refresh rate and about 20K Lux ambient light tolerance.
As a small time-of-flight sensor with a 940nm Class-1 laser and 4V ~ 5.6V power input, the TOF MINI Range Sensor works well in Raspberry Pi builds, microcontroller projects, mobile robots and compact measurement modules. The UART distance sensor is lightweight, easy to wire and supplied with a 4PIN cable.
Features
- TOF MINI Range Sensor using Time-of-Flight measurement technology.
- Typical measuring range of 0.02m ~ 4m with typical accuracy of +/- (1% ~ 3%).
- UART communication at 115200 baud, 8 data bits, 1 stop bit and no parity.
- 940nm laser with LASER CLASS 1 safety rating according to IEC 60825-1:2014.
- 30Hz refresh rate, with custom higher frequency up to 90Hz according to the official page.
- Suitable for distance measurement, robot obstacle avoidance, path planning, ceiling detection and material level sensing.
