Smart irrigation is an IoT application to regulate and efficiently use water for farming. As an IoT System Engineer:

$($a$)$ propose three $(3)$ possible input sensors that can be used to monitor any information related to the plant which can be used to manage the water consumption.

$(20$ marks$)$

$($b$)$ propose two $(2)$ suitable output indicators to help the farmer in monitoring the condition of the plant.

$(10$ marks$)$

$($c$)$ explain one $(1)$ example of network technology that can be adopted for this smart irrigation system to send the collected data to a cloud platform for the farmer's observation.

$(10$ marks$)$

$($d$)$ suggest one $(1)$ specific cloud platform that is suitable for system integration consisting of the above$-$proposed sensors$,$ output indicators and network technology.
