This project presents a rain detection and classification system implemented using the ATmega328P microcontroller. It utilizes an HW-83 analog rain sensor, an LCD for real-time display, a PWM-controlled LED for visual intensity feedback, and an external EEPROM for data persistence all controlled using AVR assembly language.
- Analog rain intensity detection
- Classification: No Rain, Light Rain, Moderate Rain, Heavy Rain
- Real-time display via 16x2 LCD
- Visual feedback using PWM-controlled LED
- Data logging using 24LC512 EEPROM
- Entire system programmed in AVR Assembly language
- Simulated in Proteus
- Code in Assembly using Atmel Studio 7.0
- ATmega328P Microcontroller
- HW-83 Rain Sensor
- LM016L 16x2 LCD
- PWM-controlled LED
- 24C512 EEPROM
- The analog rain sensor provides varying voltage depending on moisture.
- ATmega328P reads this via ADC and classifies rain level.
- Classification is shown on LCD and brightness of LED is adjusted.
- Latest classification is stored in EEPROM for persistence.
The system is tested using Proteus with a potentiometer to simulate analog rain input.
- Smart agriculture
- Weather stations
- Environmental monitoring
Developed as part of CS-430: Microprocessor Programming and Interfacing
