  In the next few years, smart farming will reach each and every nook of the
world. The prospects of using unmanned aerial vehicles (UAV) for smart farming
are immense. However, the cost and the ease in controlling UAVs for smart
farming might play an important role for motivating farmers to use UAVs in
farming. Mostly, UAVs are controlled by remote controllers using radio waves.
There are several technologies such as WiFi or ZigBee that are also used for
controlling UAVs. However, Smart Bluetooth (also referred to as Bluetooth Low
Energy) is a wireless technology used to transfer data over short distances.
Bluetooth smart is cheaper than other technologies and has the advantage of
being available on every smart phone. Farmers can use any smart phone to
operate their respective UAVs along with Bluetooth Smart enabled agricultural
sensors in the future. However, certain requirements and challenges need to be
addressed before UAVs can be operated for smart agriculture-related
applications. Hence, in this article, an attempt has been made to explore the
types of sensors suitable for smart farming, potential requirements and
challenges for operating UAVs in smart agriculture. We have also identified the
future applications of using UAVs in smart farming.
