Agriculture plays an important role in the development of the Indian economy and is essential for food security. Due to changing weather conditions, unexpected rainfall, flooding, and forest fires, agricultural activities are increasingly affected. To overcome these challenges, this project proposes a Smart Agriculture Monitoring System with Smart Weather Reporting, Flood Detection, and Forest Fire Alarm facilities. The system continuously monitors environmental and agricultural conditions using different sensors and provides alerts during abnormal situations. The proposed system uses an Arduino UNO microcontroller as the main controlling unit. A soil moisture sensor is used to measure the moisture content in the soil, while a DHT11 sensor measures temperature and humidity. A BMP180 sensor is used to measure atmospheric pressure, and a rain sensor detects rainfall. A PIR sensor detects human or animal movement. An MQ-2 gas sensor detects combustible gases, while separate fire and smoke sensors are used to identify fire and smoke conditions. A sound sensor is also interfaced to detect surrounding sound levels. All the sensors are interfaced with the Arduino UNO microcontroller, which continuously collects and processes the sensor data. The measured parameters and system status are displayed on an LCD. Whenever abnormal conditions such as excessive rainfall, fire, smoke, or gas leakage are detected, the system activates a buzzer to provide an immediate alert. Additionally, a GSM module is used to send alert SMS messages to a predefined mobile number, allowing users to receive notifications remotely. The entire system is programmed using Embedded C language to perform sensor monitoring, weather reporting, and emergency alert operations. Thus, the proposed system provides an effective solution for agricultural field monitoring, weather condition reporting, and early warning of potential environmental hazards, helping farmers improve crop safety and respond quickly to emergency situations.
