Energy harvesting brings new opportunities for wireless sensor networks


Wireless sensors enable precise measurement of microclimate conditions for optimum harvesting


By Angelo Bosoni, Marketing Manager Sensors and Tim Parker, Marketing Manager Batteries at Avnet Abacus


Sensor technologies have become an integral part of our everyday lives in the home, office, transportation, industry and in the wider environment. They provide us with essential information about how virtually everything around us is functioning, enabling monitoring and helping to improve efficiency.


There is a proliferation of sensor technologies available measuring temperature, motion, distance, pressure, fluid level, light and volume levels, air and water quality and particle count to name just a few.


As the applications and uses for sensors become ever broader there has been an emerging demand for wireless sensors. This demand often arises from applications with locations that are difficult to access due to extreme conditions such as high temperature, acidity, pressure, etc. or when laying cable and delivering power are an issue due to distance, accessibility, environmental conditions and installation costs. Wireless sensor networks are starting to see an emergence in vehicles, factories, commercial and residential buildings, agricultural and urban environments, helping to improve efficiency, safety, reliability, automation and security.
