Farmland protection against animals, fires, and insufficient monitoring is among the major issues. Traditionally, farmland surveillance involved manual monitoring, which is not effective at times of emergencies. This study proposes the design of an IoT-Based Farmland Security and Alert System meant for real-time monitoring and securing agricultural lands. Ultrasonic sensors will be used to detect intrusion attempts, flame sensors for fires while emergency buttons for manual triggering of alerts. The ESP8266 NodeMCU Microcontroller will act as the main module continuously checking data from the sensors and triggering alerts in case of any abnormality detected. Notifications are then sent out to the phone of the farmer using WiFi connection and Telegram Bot API. Additionally, there will be ISD Voice Playback Module for alerts while the ESP32-CAM module takes real-time images of incidents. According to experimentation, the accuracy of detection of intrusions and fires will be 95.2% and 96.1% respectively while the average latency of alert notification is 1.8s. The proposed system is a cost-effective, scalable, power-saving, and highly reliable solution to improve smart agriculture and farmland security.
