The aim of the project is to create an intelligent system for monitoring a plant that can be used when you are away from home for long periods of time. The system consists of an ESP32 and a raspberry PI5 used as an HTTP server. The ESP32 is connected to: a DHT11 sensor, a soil moisture sensor, an LCD, a fan and a submersible water pump. The collected data is:temperature, humidity and soil moisture. The data is sent via MQTT to the server. The server has a web interface through which the user can monitor the plant in real time, download all collected data or update environmental limits. Based on the limits set by the user via the web interface, the ESP32 will turn on/off the fan and pump to maintain optimal conditions for the installation.

The hardware components needed for the project are:

• ESP32 board - The main microcontroller of the application, it is used to connect to WiFI in order to send MQTT messages.
• DHT11 - The sensor used to collect the temperature and the air humidity.
• Soil moisture senzor - Used to get the moisture level of the soil.
• LCD with I2C - Used to display the collected data.
• DC Motor - Used to control the fan.
• Submersible water pump - Used to water the plant.
• 12V DC power supply - Used to power the pump.
• 2 relays - To control the fan and the pump.
• 10 K resistor - USed for the DHT11 sensor.
• Breadboard
• Wires
