Product description
The optical flow sensor detects motion by analyzing surface patterns. The sensor IC monitors changes in the pixels beneath it and calculates the speed and direction of its own movement from the sequence of changes over time.
The sensor is connected to the flight controller via the I2C bus, eliminating the need for a separate connection cable for each sensor when additional I2C modules are connected to the system. The 5 V operating voltage requires a suitably designed circuit. Measurements are reliably detected up to an altitude of 5 m; at greater heights, the resolution of the surface structure beneath the sensor falls below the required threshold.
In multicopters, the sensor is used for attitude control during hovering without a GPS signal or as redundancy when satellite reception is disrupted. In ground-based robots, it also improves position holding on level surfaces. The sensor makes indoor robot navigation more precise where structures are present on floors or walls; however, it provides no usable measurements on smooth, featureless surfaces.
During installation, the sensor requires a flight controller board with an I2C connection, such as an APM2 variant or compatible systems. The operating voltage is supplied by the controller or an onboard battery providing 5 V. Calibrated or calibratable firmware in the flight controller is required to integrate the sensor values into attitude control algorithms.
Safety information
The sensor must not be connected to household mains and is intended exclusively for building prototypes and for testing and development purposes involving aircraft and mobile robots. Do not look into the sensor window when the sensor is powered. Work on or near electrical installations must be carried out by qualified electricians; if you are unsure, consult a qualified electrician before commissioning.
