Solar Garden Deterrent – a quiet post that covers the yard after dark

Sunlight charges it, and a passive infrared sensor sweeps a 110 degree arc reaching roughly 30 feet. Anything moving through that field sets off a 2.5 second ultrasonic pulse paired with a light flash, after which the unit drops back to standby. Push the spike into soil or fix it to a flat surface.

Why choose this deterrent?

Netting and fence panels protect exactly the line you build them on, and they are visible from the kitchen window. A sensor post watches open lawn, a border or the edge of a pond while leaving the view alone. Charging from the sun means no cable trailing over the grass.

• Infrared detection: picks up movement across a 110 degree arc to about 30 feet out
• Charges in daylight: builds its own reserve through the day and runs on it overnight
• 2.5 second pulse: a short ultrasonic burst above most human hearing, then standby again
• Sealed against weather: rain, wind, UV and corrosion are all accounted for in the housing
• Stake or surface mount: goes into a border, onto a shed roof or beside a path

One low post in the planting, minding the yard overnight.

Strip the protective film from the solar panel before the first day out, otherwise it will never charge properly. Aim it along the route animals already use, and clear tall planting away from the sensor face. Let it take a full day of sun before you expect a complete night of operation.
