Embedded IoT Flowerpot Irrigation System

This paper presents a real-time embedded system hardware design for irrigation of flowerpots. The embedded system uses a ESP32 as the hardware for this system, uses the FreeRTOS as the real time operating system and uses the IoT IFTTT platform to send warning messages to the user. The proposed embedded system controls the amount of water a plant needs based on its soil moisture levels. The system measures individual moisture level of separate flowerpots and distributes water accordingly to maintain an optimum level. Each moisture reading, environment temperature, reservoir's water level and light sensor data are shown on a digital display.
