The designed system based on IoT which is an 'IoT based smart Vehicle monitor system'. The system used to monitor the vehicle by using IoT which displayed the parameters alcohol level, smoke level, distance of object for black spot detection, rain intensity and light intensity through Wi-Fi. Automation is the used to turn the system automatic from manual in electronics thus the helps to control the parameters as per the inputs. The automation in this system used to monitor vehicle automatically using IoT. The genuine cars could not have the facilities with respect to expensive sedan cars so proposed system gives benefits to owner in low cost. For the driver safety and simplex to monitor the proposed system designed in low cost and it will flexible to all genuine cars similar to expensive sedan cars. This auto-transmission technology helps to avoid an accident which will deploy in inexpensive genuine and some sedan cars in India. © 2018 IEEE.
