Abstract

The convergence of sensing and automation technologies in agriculture has arisen as a promising means to counteract issues of water shortage, crop protection, and green farming. This work introduces the development of an embedded multi-sensor platform intended for precision farming purposes, with special emphasis on intelligent irrigation, greenhouse temperature control, and animal intrusion alert. The system utilizes a soil moisture sensor to monitor soil conditions and control an automatic water pump, irrigating only when the moisture percentage drops below 30%. The system includes a temperature sensor to control the microclimate plant, whereby a servo-controlled ventilation or shade cover adjusts whenever the temperature rises above 20 °C. In addition, the platform uses an ultrasonic sensor to sense object or animal approach towards the crop field, thus offering real-time protection against threats. Two LCD displays are used for ongoing observation of soil temperature, moisture levels, and object detection distance, providing user-friendly feedback to farmers. With these subsystems, the platform minimizes wastage of water, avoids heat stress in crops, and improves crop protection. The proposed system identifies the advantage of embedded control and multi-sensor integration in developing cost-effective, scalable, and farmer-friendly smart agriculture solutions that can aid sustainable and technology-enabled farming practices.
