The SF11/C is a long-range (0-120m), light-weight laser altimeter that is designed for above-ground level measurement from UAVs. This sensor provides accurate and fast altitude (AGL) measuring capability, regardless of terrain. It includes digital (serial and I2C) and analog (12 bit) outputs along with a micro USB configuration port.

Key Features:

• Easy to configure using the built-in menus and LightWare Terminal software
• Fully calibrated and ready to run
• Complete with power, interface and micro USB cables.

Typical applications:

• Warning of FAA height limits.
• Precision photography.
• Terrain following.
• Assist with takeoff, landing and hovering.
