How It Works

The Wheat Germination Monitoring System operates by utilizing an Arduino NANO microcontroller as the central processing unit to gather environmental data and provide real-time feedback. Connected to the system is a DHT11 temperature sensor, which continuously measures the ambient temperature and relative humidity surrounding the wheat seeds. The Arduino processes these incoming sensor readings against pre-defined thresholds ideal for wheat germination. When the environmental parameters drift outside the optimal range, the microcontroller triggers output devices to alert the user. Specifically, text data regarding the current temperature and humidity is sent to an LCD RG1602A I2C display module for visual monitoring. Simultaneously, a piezoelectric buzzer acts as an auditory indicator, emitting tones or beeps if conditions require immediate attention. The entire circuit is assembled on a breadboard using jumper wires to connect the components, and power is supplied reliably to the system via a 5V power adaptor. Through this continuous cycle of sensing, processing, and outputting, the system helps ensure that wheat seeds are kept in stable, highly favorable growing conditions.

Frequently Asked Questions

Can I use a different microcontroller instead of the Arduino NANO?

Yes, but you would need to ensure the board supports I2C communication and has enough digital/analog pins to connect both the DHT11 sensor and the buzzer.

How does the LCD connect to the Arduino using only a few wires?

The LCD utilizes an I2C interface module, which reduces the required wiring down to four main connections: power, ground, SCL, and SDA.

What power source should I use for the project?

The system relies on a standard 5V power adaptor to safely and steadily power both the Arduino NANO and the connected display and sensors.
