The goal of this project was to create a Spray Water Gun for use in the garden that would be ergonomic, fun to use and involving the use in some technology.
The device at the top of the nozzle is a laser measuring tape. This device is connected to the motor inside the water tank. The laser and the motor communicate, so when you pull the trigger, only the amount of water needed to get to the plant that is being aimed at is shot out.
The water gun is battery powered, but when hooked up to a hose, it can be used as a spray nozzle too.
