What can Robo-Tank do for you?

The Robo-Tank Aquarium Controller is designed to offer unmatched flexibility and cost efficiency for aquarium enthusiasts. Supporting non-proprietary equipment and sensors, this aquarium controller ensures you're not locked into expensive, specialized components. With a wide range of ports—including a pH port, 16 AC outlets, 2 AC backup ports, 6 DC ports, 8 PWM/analog ports, 6 sensor ports and 2 temperature ports—the Robo-Tank Aquarium Controller can handle all of your tank’s needs, from dosing pumps and lights to heaters and water valves. Its support for common, readily available sensors which are plug and play makes integration quick and easy.

Built with modularity in mind, the Robo-Tank Aquarium Controller is split into three key components: the main controller, the sensor extension, and the equipment extension. This architecture allows for streamlined setup and efficient management of your aquarium's systems. Powered by a Raspberry Pi, the controller conveniently plugs into the main unit, offering powerful real-time processing and seamless control over AC outlets, 12-24V DC devices, solenoid valves, fans, and more. Whether you're controlling basic equipment or more advanced setups like dosing and stirrers, Robo-Tank’s versatile aquarium controller design gives you the flexibility to expand as needed.

Paired with the Robo-Tank web app, managing your aquarium becomes even more effortless. With features like scheduling, monitoring, and logging, the web app works hand in hand with the aquarium controller to give you complete control over your tank’s environment. With a 12V or 24V input and the ability to handle up to 5 amps, Robo-Tank delivers reliable power management across your entire system. Its universal connectors, which can be easily secured with a simple screwdriver, make installation a breeze. For hobbyists and professionals alike, Robo-Tank is the ultimate aquarium controller solution, offering the adaptability and power to meet any challenge while keeping your costs down.

The controller is essentially a shield for any Raspberry Pi with a 40 pin I/O header. If you use a Pi 3 or 4 two of the edges line up with the controller board so you have access to the USB ports, Ethernet, HDMI and audio ports externally when the board is put in a case. You can use a Pi Zero W or Pi Zero 2 W but won't have external access to its ports.
