Air Quality Monitoring System Based Internet of Things (IoT) Using LPWAN LoRa 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 ATmega328PAU as a controller, DHT22 sensor for temperature and air humidity, MQ7 sensor for CO gas, MQ135 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 xc2xb1 0.8 xc2xb0C, humidity xc2xb1 3.1 % RH, CO xc2xb1 10 ppm and CO2 xc2xb1 16 ppm. The results of sensor data are stored in the Antares cloud and displayed on Android.

LoRaWAN for Smart City IoT Deployments: A Long Term Evaluation LoRaWAN is a LowPowerWide Area Network (LPWAN) technology designed for Internetof Things (IoT) deployments; this paper presents experiences from deploying a cityscale network across Southampton, UK. This network was deployed to support an installation of air quality monitors and to explore the capabilities of . This deployment uses a mixture of commercial offtheshelf gateways and custom gateways. These gateway locations were chosen based on network access, site permission and accessibility, and are not necessarily the best locations theoretically. Over 135,000 messages have been transmitted by the twenty devices analysed. Over the course of the complete deployment,     72 . 4     of the messages were successfully received by the data server. Of the messages that were received, 99 were received within 10   s    of transmission. We conclude that is an applicable communication technology for cityscale air quality monitoring and other smart city applications.
