Application of IoT with PIR and Air Quality Gas Sensors for Classrooms and Buildings

These days, three modules are expected to be used to control the lights and fans in the classroom. The common sensors are used in situations where the energy safety and efficiency of the electricity is necessary. In all of these circumstances, the sensors can be burglary alarms or surveillance cameras that automatically turn on when they detect nearby motion. This can be used for saving energy consumption by turning off lights and fans in a building as it no longer can detect any activity and is frequently used. The PIR sensors are lightweight, low-powered, low cost, and simple to use. In most cases, they arrive with a white mask. By detecting temperature differences between locations, they may detect movements. In addition to the PIR, the circuit also contains an oxygen analyzer, an air quality gas sensor, and a GSM module so that we may receive a message on our phones letting us know how often energy is being utilized and conserved as well as how well the ventilation is working in that location. We can figure out the amount of oxygen circulating in the environment using an oxygen analyzer. Furthermore, we can identify the presence of various harmful gasses in the environment by employing an air quality analyzer. We can maintain a clean and clear atmosphere with the guidance of the oxygen analyzer and the air quality sensor incorporated into the system. The PIR sensor circuit will detect human activity, and rely on how it responds, it will transmit the data acquired to the Arduino controller, which will control the switching.action and the following sensors like air quality sensor, oxygen analyzer, and GSM module helps to manage the proposed method so that it aids in the consumption and savings of electricity in the classrooms and building. With the help of this suggested method, we are able to advance our extraordinary environmental healing with air.
