  24. 24. The pollution level in an area should be indicated which became the primary goal of the project.
  25. 25. Pollution Sensor :</li></ul>* A smoke sensor is used to detect the level of the smoke out of carbon dioxide which is then indicated using bar level displays.<br /><ul><li>Conversion mechanism :</li></ul>* Comparator IC’s <br /><ul><li>Pollution Level Indicator.
  26. 26. This would finally indicate the level of pollutants (CO/CO2) in a chosen area.</li></li></ul><li>Eliminate The Dragon !!!<br />Index:<br /><ul><li> Introduction
