Abstract :
Air is an important factor in life. Poor air quality can support the life of all creatures from humans, animals to plants. Air pollution is defined as a decrease in air quality so that the air experiences a decrease in quality in its use and can finally be used again as appropriate. To determine air quality, a tool is needed as an air quality monitor. The IoT prototype in designing or measuring air pollution using MQ 7 and MQ 135 works by being controlled by an ATmega 328 microcontroller IC with a control system made using C language. The programming language is made using Arduino IDE software. The hardware on the air quality monitoring prototype consists of a series of input and output circuits, namely, the MQ 7 sensor to detect CO gas and the MQ 135 sensor to detect CO2 gas. The display uses a 20x4 LCD and LEDs, and uses Blynk to display on a smartphone the entire circuit is connected to the ATmega 328 microcontroller on the Arduino Uno as a processor. Based on the tests carried out, it shows that the accuracy level on the MQ 7 sensor is 88.62% while for the MQ 135 sensor it is 84.2%, this shows that this air quality monitoring tool is categorized as feasible as an air quality monitoring medium.
