Tiivistelmä
With the rise of new low-power communication protocols and chips supporting them, it is possible to use battery powered devices to track and monitor assets in various industries and location, that were previously inaccessible for such technology. The data gained in this manner can then be used to improve and optimize different processes.
This thesis presents a firmware, and its development, for a mesh-to-LPWAN gateway prototype. The prototype device can perform temperature and acceleration measurements, as well as use GPS to get the location of the device. In addition to the data originated from the device itself, it collects measurement data from other devices connected to it by wireless mesh network, acting as a gateway. This data is then sent to a cloud backend, via LTE-M network, for storage and analysis.
The final product is supposed to be installed to a cargo containers door, where it can track the container on its trip from sender to receiver. The scope of the thesis is, however, limited to the basic gateway functionality, sensor measurement and GPS functionality, and LTE-M and mesh communications. Because of the installation location, the device is powered by a battery, which means that all features must not draw too much current.
The developed firmware worked well on the test setup that tested the devices stability and reliability over time. Also, the overall power consumption of the device is on an acceptable level.
