Large Area Sensor Networks for Environmental Monitoring Prof. Hans-Erik Nilsson

Global warming

Large area technology • large area sensing and imaging will provide – new measurement tools for sustainable industrial development and growth – a technology base for future global awareness services directed towards environmental and consumer related issues

Technology of the future • The constant pressure for more efficient industrial processes in order to stay competitive on a global market drives the development of sensor technology. • Yesterday, the driving force was primarily internally motivated by the need to reduce costs and increase quality. • Today, external considerations are growing in importance and the competition between brand names demands an active role in driving global policies for security, environment and political stability. • A large part of the sensor technology used in consumer products today was developed to satisfy yesterdays industrial needs i. e. digital cameras, MEMS solutions for accelerometers and gyroscopes, sensors for positioning and interactivity etc. Today’s industrial need is wider and tomorrow’s industrial sensor technology will be even more suited for global services on a consumer market.

Sensor technology for the information society Geographical data package into a IT service

The next step - climate Geographical data combined with sensor data Simulation models and sensor data may be used to predict the future

Power supply • Distributed sensing demands distributed power supply – Data communication is wireless • Power supply by battery or directly generated from the environment around the sensor Robust and environmentally friendly small scale energy production is demanded in order to employ distributed sensor networks at large scale

Electric power supply • Three levels – Power line infrastructure • Large power levels, power distribution over cable network, expensive infrastructure – Backup power systems • Medium sized power levels, power generated locally to ensure functionality when the power line is down – Small scale power generation • Private usage, summer houses, mobile homes, power supply to base stations for telecommunication, water pumps etc We believe that this market will increase

Generic knowledge? Power line Backup power systems system Small scale applications Tiny power supplies* Wind mills Yes Yes Geothermal Yes Maybe Yes Battery No Yes Yes Solar cells Maybe Yes Yes Hydroelectric Yes Maybe No Piezoelectric No No Maybe Yes * Tiny power supplies are intended to replace batteries in wireless systems

Why work on the small scale? • Will future energy production utilize ’the Internet paradigm’ – Local generation and storage of value – Distribution of value using the network – Flexibility to both feed and to draw value from the net • Local generation of energy will grow by itself, but it will boom if the power net would follow ‘the Internet paradigm’

Spin-off from research on large area sensor networks for environmental monitoring Energy efficient systems with low power signal processing Technology for small scale energy production Sensor technology for future remote presence in multimedia Large Area Sensor Networks for Environmental Monitoring Infrastructure for alarm functions forest fires, radioactive pollution, extreme climate changes, etc New measurement tools for environmental studies
