This is the lightweight laser altimeter SF11C developed and design by LightWave Optoelectronics,. This devices is ideal for UAV’s, (Unmanned Autonomous Vehicles) it can also serve as highly effective rangefinder in variety of application. TOF (Time of flight) system makes accurate distances measurement that does not effected by the air, change in barometric pressure, noise, ambient light or air temperature. This devices can be easily hook to your projects and ready to use with no calibration needed, you can use pins which indicated at board or using USB A to micro-B cable to read the data measured from the laser at 9600~115200 kbps bound rate.
The SF11C can be used in ground and air UAV’s detecting distance at the ground or surface, can be also used to calculate speed of moving objects or vehicles, measuring depth of material in snow, fluid, sand from above, counting passing objects in a monitoring or control system.
