Project Details
How It Works
How It WorksThe system operates through a coordinated data acquisition and display process. The DHT22 sensor measures temperature and humidity using a capacitive humidity sensor and thermistor, outputting calibrated digital data. The BMP280 sensor measures atmospheric pressure using a piezoresistive MEMS sensor and communicates via I2C protocol. The Arduino Uno reads data from both sensors, processes the raw values, formats them into readable strings, and displays them on the 16x2 LCD screen. The I2C protocol allows multiple devices (BMP280 and LCD) to share the same two communication lines (SDA and SCL). The system continuously updates readings every 2 seconds, providing real-time environmental monitoring. The pressure data can be analyzed for weather trends: rising pressure indicates fair weather, while falling pressure suggests possible rain.
Prerequisites
Basic understanding of Arduino programming (variables, loops, functions), familiarity with electronic components (resistors, sensors), knowledge of how to install Arduino libraries, and experience with breadboard prototyping. Users should know how to upload code to an Arduino board and understand basic I2C communication concepts.
