This will require new technology – like tamper-proof edge servers that can collect and analyse data far from the cloud or corporate data center. Tech analyst IDC calculates that within five years IoT gadgets will be creating 79.4 zettabytes of data. Some of this IoT data will be "small and bursty" says IDC – a quick update like a temperature reading from a sensor or a reading from a smart meter. Other devices might create huge amounts of data traffic, like a video surveillance camera using computer vision. Badly installed IoT products could easily open up corporate networks to attack by hackers, or simply leak data. It might seem like a trivial threat but imagine if the smart locks at your office refused to open one morning or the smart weather station in the CEO's office was used by hackers to create a backdoor into your network.
The transmission media used to link devices to form a computer network include electrical cable, optical fiber, and free space. In the OSI model, the software to handle the media is defined at layers 1 and 2 — the physical layer and the data link layer. Overlay networks have also been proposed as a way to improve Internet routing, such as through quality of service guarantees achieve higher-quality streaming media.
More information about flow sensors may be found in our related guide All About Flow Sensors. Level Sensors/Detectors are electronic or electro-mechanical devices used for determining the height of gases, liquids, or solids in tanks or bins and providing signals to the inputs of control or display devices. Typical level sensors use ultrasonic, capacitance, vibratory, or mechanical means to determine product height.
These include promoting more efficient use of natural resources, building better, fairer “smart cities”, and developing clean, affordable energy alternatives. "Many cities now leverage license plate readers, traffic counters, red light cameras, radiation sensors and surveillance cameras to manage day-to-day operations." In 2009, Google started testing driverless cars and in 2011, Google's Nest smart thermostat hit the market, which allowed remote control of central heating.
