Air has an important function and role in the lives of humans and other living beings. Every living things needs clean air to support its life optimally, its quality needs to be maintained. A good and healthy level of air quality is one of the main factors in creating a healthy and comfortable environment if the air quality is bad then there will be pollution that will interfere with the health of every population that inhaled. In this research, the author utilizes the Internet of Things (IoT) technology to monitor the condition of air quality levels such as temperature, air humidity, CO and CO2. The system uses ATmega328P-AU as a controller, DHT22 sensor for temperature and air humidity, MQ-7 sensor for CO gas, MQ-135 sensor for CO2 gas, LPWAN LoRa for data transmission communication and Antares as a cloud service for storing data to be displayed on Android. The test results obtained the average error value for temperatures ± 0.8 °C, humidity ± 3.1 % RH, CO ± 10 ppm and CO2 ± 16 ppm. The results of sensor data are stored in the Antares cloud and displayed on Android.
