This cabin environment monitoring system integrates multiple sensors, including DHT11 for temperature and humidity, BMP180 for atmospheric pressure, and a real-time clock (RTC) module for accurate date and time display. The data is shown on a 20x4 LCD for easy monitoring. Additionally, the system features Bluetooth connectivity that enables voice control via a paired device, allowing users to interact with the system remotely and hands-free. This makes it ideal for maintaining optimal cabin conditions and improving user convenience.

The voice-controlled environmental monitoring system continuously tracks real-time temperature, humidity, atmospheric pressure, and displays the current date and time on an I2C LCD. It uses a DS3231 RTC module to keep precise time, a DHT11 sensor to measure ambient temperature and humidity, and a BMP180 sensor to detect atmospheric pressure. The data is updated every second and displayed clearly on the LCD across multiple lines. Additionally, an HC-05 Bluetooth module allows users to send voice-based text commands via a mobile app, which are then received and shown on the LCD screen, enabling basic interaction or alerts. This setup ensures accurate environmental monitoring with the convenience of wireless communication.
