---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - With the increasing number of wildlife tourism 1.1 LITERATURE REVIEW activities, there is a growing need for technologies that enhance tourist safety while also supporting animal It focuses on developing a low-cost and efficient tracking conservation. This project introduces a wildlife tracker using system for farm animals using an Arduino microcontroller GPS & BLE technology that uses (BLE) and GPS to monitor integrated with a GPS and GSM module. The GPS module wild animals and alert tourists in real time. The system continuously records the animal’s position, while GSM involves compact tags attached to animals, integrating a GPS transmits this data to the farmer’s mobile phone through module for location tracking and a BLE chip for short-range SMS. The proposed system helps farmers locate missing communication. When a tagged animal approaches within a animals, monitor grazing boundaries, and detect unusual predefined range, nearby smartphones (with the app) detect movements. The system also ensures better animal safety the BLE signal and generate alert notifications, including and management. The hardware is lightweight, easy to warning sounds and animal information. The GPS data is also mount, and powered by a rechargeable battery. Overall, it logged for use by forest departments to study animal demonstrates how IoT technology can reduce livestock loss movement patterns. This solution operates with BLE & GPS and improve farm automation.[1] technologies , making it suitable for remote forest areas. It increases tourist awareness, reduces human animal conflicts, It presents a real-time tracking system that uses Bluetooth and animal monitoring .The proposed system combines safety, Low Energy (BLE) beacons to monitor asset location. BLE technology, and conservation into a practical solution . tags periodically send location data to a mobile application or gateway device within a defined range. Compared to Key Words: Alerts, Location Tracking, GPS, BLE, Animals traditional Bluetooth or Wi-Fi systems, BLE consumes very little power and supports longer battery life. The paper explains data transfer mechanisms, signal strength-based 1.INTRODUCTION localization, and the use of smartphones as receivers. The proposed technique ensures real-time data visualization on a Wildlife plays a vital role in maintaining the balance of our dashboard and supports multiple nodes simultaneously. It’s ecosystem. However, with increasing human interference adaptable not only for industrial asset management but also and habitat loss, many wild animals are at risk, leading to for tracking animals or equipment in forest zones.[2] frequent human animal conflicts and difficulties in monitoring their movements. Traditional tracking methods Introduces a BLE-based wireless sensor node designed to are often limited by range, high cost, and poor connectivity monitor animal health and location efficiently. The node in remote forest regions. To address these challenges, this includes sensors for temperature, motion, and heart rate, project proposes a Wildlife Tracker & Alert System using enabling health diagnostics in addition to tracking. It GPS and Bluetooth Low Energy (BLE) technologies. The communicates data to a base station or smartphone using GPS module continuously provides the animal’s location Bluetooth Low Energy technology, which significantly coordinates, while the BLE module enables short-range reduces energy consumption. The device is built for remote communication with nearby smartphones or monitoring field operation and optimized for compactness and long devices, even in areas without internet access. The system battery life. The authors discuss the firmware structure, also integrates health monitoring sensors such as energy optimization, and data transmission protocols. The temperature and heart rate sensors to track the animal’s solution demonstrates how BLE can replace costly longcondition. If any abnormal readings or risky proximity are range systems for short-range animal management tasks.[3] detected, the system sends alerts to forest officials and nearby tourists for quick action. This solution enhances The pepper focuses on detecting and tracking wild animals wildlife safety, supports behavioral study through stored near forest boundaries using sensors and image processing data on an SD card, and helps reduce human–animal techniques. It integrates GPS for location tracking and conflicts. By combining GPS precision with BLE efficiency, wireless communication to send alerts when an animal the project offers a cost-effective, low-power, and scalable crosses a geofenced area. The system uses infrared (IR) and approach to modern wildlife monitoring. motion sensors to detect movement even at night. Alerts are
