Zayd wowed the judges with his complex Z Palm Tree creation. This creative and innovative solution towards Global Goal 15, Life on Land, would enable a tree to ‘communicate’ its needs. 

Zayd has used multiple external and internal sensors to create the Z Palm Tree, including a vibration sensor to sense the tree being cut down, a flame sensor to detect the tree being burned down, a moisture sensor in the ground to detect water level and the internal temperature sensor to approximate the air temperature. With the results recorded by the sensors, the Z Palm Tree uses Bluetooth to connect to an app created by Zayd which will warn the user if the tree needs more water. It connects to the same app via the internet to warn the user of a fire, and uses speakers to give information on the air temperature, to shout for help if being cut down and to warn anyone nearby if there’s a fire. But the features of Zayd’s creation don’t stop there. He has also connected a water pump to the app so that the user can click a button to water the tree, and has used a servo and two LED matrices to create a face that shows emotion and moves its mouth when talking.
