#SmartME Sensors

One of the vertical use cases that has been implemented in the #SmartME project is the collection of city environmental monitoring data in a standard open data format. We exploited CKAN, an open source data portal software, to store and visualize the collected data.

Asynchronous plugins are used in this application for sampling environmental data and sending it to the CKAN datastore. The plugins run on top of Arduino YUN boards deployed in the Messina urban area.

The Arduino YUN is an embedded board based on the Atmel ATmega32u4 micro-controller and the Atheros AR9331 System-on-a Chip. Linino OS, a Linux distribution based on OpenWrt, runs on the Atheros MIPS processor, also supporting microcontroller-exposed interfaces to General Purpose I/O (GPIO) pins. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital I/O pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and 3 reset buttons.

In order to host a set of low-cost sensors, the YUN board has been equipped with a Tinkerkit Shield. In particular, a Tinkerkit thermistore, Ldr, and Mpl3115 have been employed as temperature, brightness, and pressure sensors, respectively. A Groove MQ9 is installed as CO sensor, to obtain information about air quality. Finally, a Honeywell HIH-4030 has been selected as humidity sensor while an Arduino KY38 captures the environmental noise level.

Using the ideino-linino library, plugins periodically sample the voltage levels of the pins to which sensors are connected. Such voltage samples are then elaborated to obtain the environmental data and finally sent to CKAN together with a timestamp and the geographical position of the node.
