 This project presents a smart plant watering system designed to operate semi-autonomously. It monitors the soil moisture and automatically activates a peristaltic pump via a latching relay to deliver water when needed. The system uses two ESP32-S3 microcontrollers connected over Wi-Fi, communicating through MQTT protocol to exchange sensor data and control messages.
 The architecture is split into two subsystems:
