IDEA Open Sensor Network Framework

Building sensor networks with cheap and well known hardware (Arduino,

RaspberryPI)

A network consist of several nodes, each one managed by a single Rpi

Each node has one or multiple Arduino station

Managing the whole network through an extensible open source framework

Data available through Web Services

NoSQL DB available for specialist data analysis

Web interface/Mobile App for user interaction

• Many proprietary solutions available

• There isn’t any widely used standard in this field

• Threre isn’t any similar framework running on Arduino/RPI

• Embrace open source community using Arduino/Rpi

• Solution applicable to many application domains

►Environment Management

►Manufacturing

►Automotive

►Energy

►Telco

►Healthcare

Use Case

Streetlights Energy saving

• Distribute several nodes along the street

• Each node can detect passing cars and turn on/off streetlights

• Every node will turn lights on based on the information gathered by the previous one

Data Storage Layer

► NoSQL database MongoDB instance hosted in the cloud on mongolab.com and configured to efficiently store large time series data.

► The implementation of this layer, for the team was an opportunity to put the hands on a new technology and gain know how reusable on a lot of different field.

► In fact, today there are many sources of data that represent observations ordered over time. For example:

• Sensors measure temperature, barometric pressure, humidity and other environmental variables.

• Financial markets generate prices.

• Industrial fleets such as ships, aircraft and trucks produce location, velocity, and operational metrics.

• Status updates on social networks.

• Calls, SMS messages and other signals from mobile devices.

• Systems themselves write information to logs.
