5. Operating Instructions
Once set up, the Hoont Motion-Activated Animal Repellent Sprinkler operates automatically:
- Motion Detection: The integrated PIR sensor detects movement within its adjustable range of 0 to 30 feet.
- Water Jet Activation: Upon detecting motion, the sprinkler activates a 5-second intermittent water jet. This sudden burst of water and motion startles animals, encouraging them to leave the protected area.
- Water Conservation: The intermittent spray cycle ensures effective deterrence while minimizing water consumption.
- Continuous Protection: The device provides 24/7 protection, day and night, as long as it has power and water supply.
