wireless sensor networks

Wireless Sensor Networks (WSN) could involve billions of sensors used in utility assets, buildings, pollution monitors, traffic control systems, and agriculture. To date, adoption has been hindered by conventional primary batteries, which cannot be fitted and forgotten for long periods. However, zero power wireless sensors are now available

The market for wireless sensor networks (WSNs) will grow rapidly from US$0.45bn in 2011 to $2bn in 2021, according to a report from IDTechEx.
