Abstract:
Rapid proliferation of the internet of things has
helped solve a myriad of problems across different
sectors. Whilst powered assets rely on their own
power source to enhance asset monitoring, a need
exists to develop an asset security system for nonpowered assets. Since an IoT device has network
layers, it can be used with the physical layer to
solve this problem. As a result, a method of
enhancing asset security with IoT was
implemented. A GSM chip for SMS and server
connection was used to communicate the battery
status and location information obtained from a
GPS chip. A method of detecting tamper on the
device was implemented through infrared sensors.
A microcontroller was the heart of the system as it
interfaced with all other devices to form the IoT
system. The result of the study was an efficient
prototype of an IoT asset tracking device which
communicates through SMS and it logs location
data to a remote server through GPRS connection.
There is room for improvement in terms of
optimizing power consumption to lengthen the
duration before a recharge is required.
