Design and Implementation of a Self-Contained Device for Monitoring and Alerting Emission: Sensor Based Approach

Abstract

The goal of this project is to create a device that can measure the pollution emitted by a vehicle by analyzing its exhaust gases. The device is designed to be self-contained and does not require external instruments or certification. It utilizes a gas sensor that detects the level of carbon monoxide in the exhaust and a microcontroller that controls an LCD display to display this information. The system consists of two parts: a sensor node and a server node. The sensor in the sensor node detects the gases, and the data is processed by the microcontroller. Additionally, the device aims to convert the heat produced by the engine into electricity. The server node of the system is responsible for checking the pollutant levels. If the gas pollutant levels exceed a predetermined threshold or safe range, the server node sends two alert messages to the users. The system is also connected to the engine’s on/off circuit, and if the user ignores the warnings and continues to operate the vehicle without repairing it, the engine’s on/off circuit will be cut and the vehicle will stop moving. The user will only be able to use the vehicle again once they have repaired the pollution in the engine.
