OpenSprinkler Bee (OSBee) 2.0 is an open-source, WiFi-enabled, universal sprinkler controller. It is suitable for garden and lawn watering, flower and plant irrigation, hydroponics, and other types of watering projects. It comes with a built-in ESP8266 WiFi chip, a 128x64 OLED display, a laser cut acrylic enclosure, and can switch up to 3 zones independently. It is primarily designed for latching solenoid valves, but can also switch non-latching valves (e.g. standard 24VAC sprinkler valves), low-voltage (5~12V) fish tank pumps, and other types of low-voltage DC or AC valves and pumps. All of these are powered from just a single USB port. This is why it's called a Universal sprinkler controller. It is made possible by leveraging a unique boost converter and solenoid driver circuit design.
