TOF MINIF Range Sensor
0.02m ~ 20m typical measurement range
TOF MINIF Range Sensor (B)
0.02m ~ 5m typical measurement range
The TOF MINIF Range Sensor is a laser ranging sensor based on Time-of-Flight (TOF) technology. Built-in controller and ranging algorithm, providing a measurement range of 0.02 ~ 5m/20m with an accuracy within ± (1% ~ 3%). Supports UART communication and features an ultra-narrow FOV for long-range measurement. Suitable for both indoor and outdoor environments, with ambient light resistance of up to approximately 100K Lux, enabling applications such as distance measurement, robotic obstacle avoidance, path planning, ceiling detection, and material level measurement.
