Then, the radio was the star…

Yesterday, we wrapped up the Arduino summer camp with using Xbee radio communication to send data from the Arduino node to the laptop. It involved some soldering to build the radios from inexpensive components. It was a first for Katie and me, and Katie produced the most perfect little ‘hershey kisses’ dollups right away. Way to go!

How it all started:

Soil moisture wireless sensor network deployed in blueberry barrens

Today, after a year of discussions, finding funds, designing, ordering, building, testing, in the lab and in my garden, we finally deployed the 3-node wireless soil moisture sensor network in a blueberry barren at Cherryfield Farms Inc. It’s up and running!

The individual nodes consist of an Arduino node, a solar panel for battery power, an Xbee radio for wireless communication, and a soil moisture sensor each. The Arduinos are enclosed in weather-proof boxes, and the soil moisture sensors are deploy horizontally at 3.5 inch depth since the root system of blueberries is shallow. The base station is a Raspberry Pi that is powered off an in-field power station that Cherryfield Farms uses for its controlled irrigation system, and also uses an Xbee radio, writing the data locally to flash.

Everything is up and running, and the sensors send data every 5 minutes.

Field testing of Soil Moisture Geosensor Network

After building it in the lab over the winter, and indoor testing, we deploy the soil moisture geosensor networks for field testing outdoors today.

Sensing a color and display the RGB color via the LED

Today’s second Arduino summer camp was about reverse engineering resistors and LEDs that show different colors. One project was about a 3-part RGB sensor and displaying the sensed RGB color as LED light.

Arduino Summer Camp Kickoff

Today, we kicked off an Arduino learning summer camp. J.C., our resident expert, showed us to get started with an Arduino starter kit, and get the first sensor sensing and the first LED blinking. However, it felt a bit like a flash back to electrical engineering classes, with resistors, pins, and analog inputs…. anyway.

We have 3 CS undergraduates, one SIE graduate and a few faculty participating.

Dear Colleagues,

The last two decades have seen unprecedented advances in the development and miniaturization of a variety of sensors, as well as inexpensive, small computing platforms, and a plethora of wireless communication media. These technological developments have lead to the related research areas of geosensor networks and the sensor web.

Geosensor networks are wireless, ad hoc sensor networks that employ recent research progress from electrical engineering, computer science, and spatial information science to create small devices, running compact, space and time-aware algorithms for live, in-place analytics. Sensors can range from stationary environmental sensors to drones or autonomous vehicles collecting imagery data, or even to humans acting as sensors using smartphones. The sensor web, on the other hand, realizes the idea of a standardized, interoperable platform for everyone to easily share, find, and access sensor data that is based on space, time, and other attributes, similar to easily searching for and sharing information on the Internet. Today, we see further growth in the availability of massive numbers of real-time sensor streams, precipitating a need for real-time analysis. From a practical perspective, geosensor networks can be simply defined as “networked geosensors”, or networks of sensor nodes deployed in geographic space with various communication topologies. Such geosensor networks enable us to observe, reason about, and react to events in space and time in near real-time. To truly leverage this ubiquitous sensing infrastructure, research advances relating to the sensor web are of utmost importance, enabling easy access, sharing, and interoperability.

We invite original research contributions on all aspects of geosensor networks, the sensor web, and their applications, and, particularly, encourage submissions focusing on the following themes for this Special Issue.

  • ž   Formal foundations of geosensor networks
  • ž   Decentralized spatial computing and spatial self-organization

  • ž   Crowdsensing for emergency applications and humans as sensors
  • ž   Cooperative sensing using drones, and UAVs
  • ž   Experiences and lessons learned deploying geosensor networks
  • ž   Geosensor network and sensor web use cases: government, participatory
  • ž   GIS, health, energy, water, climate change, etc.
  • ž   Platforms, architectures and open source software for geosensor
  • ž   Networks and the sensor web
  • ž   Geosensor networks, ontologies and standards
  • ž   Benchmarking geosensor networks
