Contact UsHome / What sensors are on the optical flow module
An Optical Flow setup requires a downward facing camera and a downward facing distance sensor (preferably a LiDAR). These can be combined in a single product, such as the ARK Flow, ARK Flow MR and Holybro H-Flow, or they may be separate sensors. It can be used to determine speed when navigating without GNSS — in buildings, underground, or in any other GNSS-denied environment. Exploring the capabilities of optical flow sensors by transforming an old optical mouse into a handheld motion tracking device. This all-in-one design simplifies installation, while the onboard infrared LED enhances.
