This is an award winning project model I made for a group. This is a pole used to scare birds away from farm crops, it operates with solar energy in which the energy is stored in a battery to work in the night or without sunlight. There is a sensor on top that senses the birds and scares them away with a buzzing noise and a laser beam (you can find this description on my YouTube , hyiahcreative) you can follow me on @hyiah_creative.
