Design and Development of $\text{CO}_{2}$ Sensor as Portable Controller

In the present scenario, the atmospheric air impacts human health, energy and causes illness because of prolonged exposure to the polluted air. Carbon dioxide (CO
2
) is the byproduct of human lifestyle and industrial revolution. Due to the actuality that high ranges of carbon dioxide in the air can reason critical ailments of the human frame, it is essential to screen this stage inside the room wherein people are present. High concentration levels of CO
2
in a poorly ventilated environment can cause harmful reactions in people. In Order to tackle this problem a Micro Electro Mechanical System (MEMS) carbon dioxide sensor is designed and fabricated by surface micromachining technique which has low cost and good efficiency as compared to the sensors presently available in the market Waveshare MQ-135 gas sensor. Eventually, the developed product with the prototype model ensures to allow the operator to display the concentration of CO
2
inside the closed environment.
