How to scares the animals in your garden with a self made animal repeller (Water Alarm System)

How to scare the animals in your garden or protect the fish in your pond from Mr. heron using a motion detector and water sprinkler?
Most important parts i used:
- Motion Detector 230V with waterproof junction box
- Water Sprinkler
- Water hose with quick fit connectors
- Electric Water Valve 12V DC
- Power Adapter 230V AC to 12V DC
- Waterproof Power Outlet Socket
- Sonoff WiFi Switch ( i used a 4 channel but you can also use a 1 channel)
I connect my system to a Sonoff WiFi switch so that i can set a schedule with an app but it`s also posible to easily connect the system with permanent power without WiFi switch but then the system is always on
