In today’s era, wildlife and forest departments are facing the problem of movement of animals from forests to residential area. The number of trees has reduced drastically which creates an unhealthy environment for animals and for humans. Findings of a survey suggest that 80% losses are caused due to wildfire. This could have been avoided if the fire was detected in the early stages. This paper suggests a system for alarming the authorities in case of a bushfire. Nowadays, IoT (Internet of Things) devices and sensors allow the monitoring of the forest ecosystem, such as temperature and smoke. Arduino platform based IoT enabled fire detector and monitoring system is the solution to this problem. In this paper, fire detector using Arduino NANO is built which is interfaced with a fire sensor and smoke sensor. Whenever fire occurs, the system automatically senses and alerts the administrator by sending the message on the user’s mobile device.
