The ultimate automatic door for every chicken farmer! This automated chicken coop door opener features a waterproof function, sturdy design, and a light sensor that safely secures your chickens at night and grants them freedom during the day. Enjoy plug-and-play technology with an installation that takes no more than 10 minutes, requiring no complicated wiring. It offers a minimum 3-year battery life under all conditions using 3 AA batteries (not included), which are easily replaceable in minutes—no solar cells needed. The door is easily programmable via a simple button interface. It opens automatically in the morning and closes in the evening. You can set a timer or use the built-in light sensor (LUX). Its durable, weather-resistant design operates reliably in snow, rain, and dust, with a working temperature range from -15°F to 140°F (-26°C to 60°C). Built to withstand high and low temperatures, the door and its waterproof battery case ensure year-round outdoor performance. It is widely applicable for backyards and farms, suitable for most poultry like chickens and ducks, and can also be used for small pets such as cats and dogs.
