Abstract:

            A significant resource for human life is the forest. A forest consists of thousands, maybe even millions of different species of animals and plants that coexist in a sophisticated “ecological mix”.The greatest threat to forests in densely populated emerging nations like India is the use of illegal and unauthorised methods for cutting down the trees and forest fires caused due to environmental changes. As a result, many devices are developed  in recent years based on Internet of Things(IOT) for a real time intrusion detection and fire detection system. In this paper,We use laser detector to protect forest from illegal entries such as human beings, wild animals etc. Flame sensor along with the other thermal sensors are used to detect Fire in and around the periphery of the forest.The LoRa(Long Range) module is also incorporated in the system to wirelessly transfer the sensor data to the nearest forest officials.Compared to different wireless transmission technologies LoRa transmits data to a longer range.

Key Words: Intrusion detection, PIR sensor, LoRa and fire detection.
