The illegal movement of valuable trees such as sandal wood trees in forests poses a severe risk to natural reserves and it instigates a great loss to our country’s wealth. Almost 24,000 square miles has been lost due to deforestation in the past decade. This paper proposes an antipoaching system using NodeMCU based wireless system that uses 3- axis MEMS accelerometer (GY-61) and tilt sensor for detecting the falling of trees due to cutting of trees or natural calamities and Flame sensor, fire retardant for detecting and controlling the fire. In this project we use NodeMCU which has an inbuilt Wi-Fi module which covers a distance of around 300m range, is used in this project for cost efficiency and also NodeMCU enables the communication with neighbor nodes like client and server nodes. This protocol is used to monitor the trees even using a single node from the server system. The solenoid valve is used to spray the fire retardant to control the fire. Some IOT modules can also be used in this system to provide accurate information and remote monitoring of trees.
Due to increase in aggregation of vehicles at the road junctions and to avoid accidents at times, there is a need for a smart traffic light controller which can detect vehicle density on the road. This proposal involves image acquisition, vehicle detection and vehicle density through progressive image processing operations applied on the captured images using MATLAB. For multiple road implementations, we use a movable web-camera controlled by a stepper motor and data is stored and further extended for embedded applications. Smart Traffic Control can be achieved by Image acquisition, Edge detection, Image Enhancement techniques and Traffic Regulation.
