According to industry reports, sensors are turning into the greatest and quickest developing markets, tantamount with PCs and specialized gadgets markets. You discover sensors in cell phones, autos, security frameworks and even regular articles like espresso creators! Aside from purchaser gadgets, these are additionally a vital piece of the Internet of Things (IoT), restorative, atomic, guard, aeronautics, apply autonomy and man-made consciousness, farming, condition observing and remote ocean applications.
BLE beacons are the cornerstones of indoor positioning. With this technology, the device can detect when in range of a beacon and even calculate its position if in range of more than two beacons.
Positioning based on BLE developed in the last couple of years. First prototypes were only able to detect which Beacon is closest to the user, but today we are able to use distance data from many beacons and position the user in 2D space on indoor map. Accuracy does vary depending on circumstances but can be as good as within +-1.5 meters.
This technology will develop further offering even more precise positioning. This will be achieved by utilizing as well the use of magnetic field detection, gyroscope, accelerator meter and Near Field Communication (NFC) chips.
