Problem :
Animals, especially deer, are notorious for eating crops, flowers, and shrubs. Many powder-based solutions fail from dew or rain and need to be reapplied. Motion detection solutions that spray water require a connection to a water hose and can be unattractive.
Solution :
A motion detecting unit that will sense an object within 6 feet and begin spraying in a 180-degree pattern. Water is stored in a reservoir and can be easily filled.
Innovation :
Initial prototype included using an Arduino to process the signals and control the pump and servo motors. Once we <remixed> the design we upgraded to a custom printed circuit board and reduced the amount of wiring required. Power is provided from a custom solar panel and battery bank.
Specifications :
- The unit is all-weather capable.
- Powered by lead-acid battery and charged by a solar panel neatly installed over the unit.
- 365/7 days a week battery capacity due to automatic solar charging.
- Leverages an infra-red sensor-based sentry system with 180-degree sensor coverage
- Integrates an 8-bit microcontroller with a complex algorithm to detect wild animals and then activate a water spray system.
- The system has 180-degree coverage and a range of 16 feet.
- 2.5 gallons water storage capacity.
- Low water level and battery charge alarms with visual LED indicators.
- When the unit needs water or is not charging properly you will be alerted by an alarm and visual LED indicator.
