How the URI Laser Scarecrow Operates
The system’s core function is to project a green laser beam that continuously moves in unpredictable patterns. This motion is crucial in preventing birds from becoming accustomed to the device, thereby maintaining its efficacy over time. The laser operates automatically from dawn to dusk, thanks to an integrated light sensor that detects ambient light levels, ensuring it runs only during the hours needed most.
Key Features and User Benefits
Versatile Placement Options
Designed to adapt to various agricultural settings, the URI Laser Scarecrow can be installed at strategic heights and angles depending on the crop type:
- Corn Fields: Positioned at tassel height for maximum effectiveness.
- Berry Crops: Mounted above the canopy to sweep across the plants.
- Vineyards: Adjusted for varying cluster heights to protect entire grapevines.
Automated and Energy-Efficient Design
A microcontroller manages the laser’s patterns, creating a dynamic deterrent that birds cannot ignore. The system’s energy efficiency is enhanced by its ability to operate within the required time frames, reducing power consumption while maximizing protection.
