Overview
Meskernel PTFS-100-100Hz is a high frequency distance sensor and laser rangefinder module designed for drone/UAV and industrial applications. It uses pulsed laser technology at 905 nm (Class I) to measure distance by timing the round-trip flight of emitted pulses. The module offers strong anti-jamming ability, supports secondary development, and provides customizable measurement frequency within the specified range. It is suitable for indoor and outdoor use.
