The project integrates an Arduino with a DHT11 sensor for measuring temperature and humidity, along with an RTC DS3231 module for maintaining real-time clock functionality. The Arduino periodically reads data from the DHT11 sensor and RTC module, calculates the heat index, and sends all data (including date, time, temperature, and humidity)
