IOT PROTOTYPE AIR QUALITY MONITORING USING LORA COMMUNICATION SYSTEM ON FREQUENCY 433 MHZ

The Internet of Things (IoT) is one of the technologies in the telecommunications sector that is currently developing. One of the IoT applications that can be used is daily air quality monitoring. Indonesia is a vast country with diverse ecosystems, according to WHO, Indonesia has moved from the cleanest air quality country to one of the twenty most polluted countries in the last two decades. For now, information regarding exposure to air pollution in Indonesia is still limited. The implementation of this project aims to provide a solution by designing a device that can monitor air conditions in real time. This device will be equipped with several sensors relevant to air quality, namely PMS5003 to detect concentrations of PM 2.5 and PM 10 in the air, MICS-6814 to detect levels of carbon monoxide (CO) and nitrogen dioxide (NO2) gases, MQ-131 to detect levels of carbon monoxide (CO) and nitrogen dioxide (NO2). ozone gas (O3). The device will upload it to a web dashboard that can be accessed by the public, on the web it will display the Air Pollutant Standard Index (ISPU), which is a standard for measuring air quality that has been made by the Ministry of Environment and Forestry (KLHK). This final project will also explain the performance of LoRa communication on the prototype against distance and line of sight.
