Implementation of an Automated Environmental Signal Conditioning Circuit in Automobiles

N ow days, the world is improving in utilizing technology especially in automation and everything is running with automation. The role of automation in the field of automobiles is increasing day by day. In this paper, an automated system for the window glass is proposed to close and open based on the amount of the air concentration and purity inside and outside the car. When the interior of the car has high amount of CO
₂
level along with suspended particulate matter (SPM) and Chlorofluorocarbon's (CFC) which causes suffocation, a trigger is given to the motor which is placed in the door window and the window will come down to let the fresh air come in. There will be an external sensor which is located on the posterior side of the car, so on reaching a polluted area it will be the first sensor to send a trigger signal to the controller. The controller will trigger the motor which will close the window. Another sensor is fixed in the windshield which on detecting the rainfall creates an alert signal to the controller to close all the side windows. Thus, the proposed methodology is basically the integration of rain sensor and chemical sensors working for maintaining human health and comfort automatically to reduce efforts of human and also avoid the risks of accidents in automobiles.
