Story

Introduction

Our group was task by our lecturer to create a project using m5stack fire IOT device. M5stack fire is a IOT device that is able to connect to a series of component to carry out a range of things. Early on the project we have decided on using what we are given to do a plant monitoring system.

How it works ?

The plant monitoring system uses 2 m5stacks. One of the m5stacks is able to measure the temperature and the pressure of the plants. When the temperature is too high the servo motor will move. The servo motor is designed to be connected to a pulley system that aims to provide shelter for the plant. When the pressure of the plant is too high the there will be a notification sent to the user through IFTTT software. The temperature and Pressure as well as if its suitable for the plant is indicated in the GUI(graphical user interface ) or UI of the m5stack.

For the other m5stack it is connected a earth sensor and servo motor. This m5stack is design to get the hydration of the plant. If the plant is lacking in hydration this m5stack will move a servo to water the plant. If the plant is lacking in hydration there will also be a notification sent to the users handphone using IFTTT software.
