Smart City Project to Monitor Environmental Parameters
Smart City project, which has been developed by several
companies and institutions aims at designing, deploying
and validating in Santander and its environment a platform
composed of sensors, actuators, cameras and screens to
offer useful information to citizens. Waspmotes have been
deployed to monitor different parameters such as noise,
temperature, luminosity and CO.
The city divided in different zones. Each zone had a Meshlium to gather the data from the
sensors and the number of sensors depended on the area to cover. Each zone had different
network parameters, creating independent networks that work on different frequency
channels not to interfere with each other.
Sensors were deployed in different locations within the city of Santander, measuring
different parameters:
• Temperature → 665 sensors
• Luminosity → 585 sensors
• CO → 20 sensors
• Noise → 65 sensors
Temperature nodes are able to measure ambient temperature within the range [-40,125] ºC.
They provide the network with a high accuracy and a very low power consumption, fitting
the requirements of the project. Luminosity nodes are capable of measuring the intensity of
light received. It allows to detect light/darkness in the same way as a human eye would
detect it. These sensors are connected directly to Waspmote without a sensor board.
CO nodes detect changes in concentration of Carbon Monoxide from 30 to 1000 ppm.
Pollution maps can be created using this sensor and its output. This sensor is connected to
Waspmote through the Gas Sensor Board.

Noise nodes may monitor noise pollution since they include an omni-directional microphone
with an almost flat response in the whole frequency range of human hearing, between 20Hz
and 20 KHz. This sensor is connected to Waspmote through the Smart Cities Sensor Board.

Send the environmental information. On the other hand, IEEE 802.15.4 protocol is used to
experiment within the network. Application proposes a unique experimentation facility since
all the nodes within the network can be used to test new algorithms while citizens still get
information from their environment.

Each sensor has two radios for communicating at 2.4GHz. On the one hand, DigiMesh is the
protocol selected to if any of these 4 parameters goes above a threshold, then the system
analyzes the information and may react sending an alarm to the central node (Meshlium in
this case). In order to know where this sensor is located, each Waspmote can integrate a GPS
that delivers accurate position and time information.
One of the main characteristics of Waspmote is its low power consumption:
• 9 mA, ON mode
• 62 μA, sleep mode
• 0,7 μA, hibernate mode
Waspmote is sleeping most of the time, in order to save battery. After some minutes
(programmable by the user), Waspmote wakes up, reads from the sensors, implements the
wireless communication and goes again to sleep mode.

Smart Santander project has created an interactive map to view the different values that
sensors are returning in real-time. In this way, citizens can consult environmental conditions
around them.

As a result of this project, environmental parameters can be monitored for further study as
well as citizens can also know them thanks to real-time maps available for viewing.
Furthermore, Smart Santander project is a large-scale network for experimentation that
allows researchers from all over the world to test different algorithms in a real environment.
