Abstract:
Air pollution consists of a mixture of solid particles and gases in the air. Gases from septic tanks, car emissions, and chemicals from factories, dust, pollen, and mold spores may be suspended as particles. The effect of air pollution has many bad things, and some of them may cause problems for our health, such as asthma, cough, and lung disorders. In addition, the pollutant can cause global warming, acid rain, and disturbing plant growth. Basically, a human being cannot determine whether the air is good or not. Hence, it is necessary to have a tool that can measure the air quality. We aimed at designing an IoT-based septic tank monitoring system. The septic tank will be interfaced with a DHT22 sensor, MQ7, MQ135, and ultrasonic sensor to monitor and collect data that will be sent to the Atmeg328p microcontroller for processing purposes. Our aim is to enable users to monitor the level of hydrogen sulfide and Carbon Monoxide which is higher than 100 PPM. The system will send alert message to authorized users to make them know that the hydrogen sulfide and Carbon Monoxide has become harmful. The system will make it possible to pump the neutralizer in the septic tank until the hydrogen sulfide gas reaches the level which is less than 100 PPM. The system will enable the users to monitor the status of septic tank so that when it is greater than 80% of the human waste, an alert is provided to the authorized users informing them that the is about to be full. The last phase of the system will consist of measuring the level of the neutralizer, to ensure that when it is less than 20% of neutralizer, the system will send an alert message to authorized users informing them that the neutralizer is about to be finished. All the monitored data will be sent to the platform using GSM.
