Architecture

Arduino(s) and PC are forming an “Aquino device”

Arduino is providing measurements over the serial interface in JSON format. It is also using the same way of communication to receive orders to control aquarium system.

Note

There is an idea to allow for more than one Arduino connected to the PC. Each Arduino (with the set of sensors) is used to measure and control a different tank. This would lower the cost of potential multitank installation

PC is a Linux box. It is temporarily collecting the data in database (redis) and storing them on the server when web is available. PC might be configured using web interface. Configuration is stored in database.

Note

Typical Aquino device will use Raspberry Pi

There is also an LCD display to show measurements next to the tank.

REST API server will work as an invisible layer between client applications and the device. It is providing the way to save measurements, serving data to the clients, passing orders from client to device.

Everything which is displaying collected data is considered a Client. Be it mobile app (Mozilla WebApp will be written as a part of ths project) website or desktop app.

WebApp. Part of the Aquino is an Open WebApp to receive notifications and control the devices and notifications on all possible clients (mobile/tablet/desktop)

Note

Why mozilla webApp? As it will work on any device

By any, do you imply any device that could run mozilla browser? i.e. not iphone? Almost every smartphone is (or will be at the time this project will see daylight) able to run this type of webapps. It’s already possible on iOS, Android. Also, there will be an open REST API which will allow to write apps for any system.
