The current temperature and humidity will be monitored and displayed on a 7-segment display connected to an Arduino Uno

The AM2320 sensor, which communicates via I2C, will be used

The sensor's functionality will be simulated with the help of a second microcontroller that will implement the sensor's functions

The settings for the activation/deactivation thresholds of the fan and humidifier will be adjusted through serial communication

The user can dynamically modify the operating thresholds as needed, without requiring the device to be reprogrammed

Based on the data received from the MC that's simulating the sensor, the system will control a fan to regulate the temperature and humidity according to the thresholds set via serial communication

The fan will be controlled using a relay

The fan will be simulated using an LED

Special attention will be given to the programming and connection of the 7-segment display to ensure a clear and accurate reading of the temperature and humidity values

Each of the two values (temperature and humidity) will be alternately displayed on the device (consisting of two separate 7-segment displays) at 2-second intervals

The system must provide feedback to the user to confirm the receipt and implementation of the new settings via serial communication

This feedback is implemented throught a temporary change in the display
