Forest fires are common hazards in forests that harm both wildlife and the environment. It could be avoided if a strong system was deployed in forest areas to detect fires and alert firefighting authorities to take immediate action. The goal of this project is to create an IoT-based forest fire detection system that detects fires and sends an emergency alert to authorities. Because network bandwidth is typically very low or non-existent in forest areas, a GSM/GPRS module is used to communicate with an IoT server. As a result, a 2G network is preferable for communicating with the server. Components to use Arduino Nano Flame sensor Dot matrix Perf board SIM800L GPS/GPRS Module 3.7V Li-ion Battery
