Abstract:
Research has been carried out on the design of a monitoring system for air
quality parameters (temperature, CO, LPG and dust) whose data is integrated in real time. The measuring instrument uses the Arduino Uno R3 microcontroller base. The MQ-9 and MQ-5 gas sensors are used to measure air pollution, while the LM35 and DSM 501A sensors are used for temperature and dust. This system is also connected with Xbee S2 as a
data sender and receiver based on WIFI. The voltage source is connected to a 10 W solar panel which is regulated by the charger controller so that when the battery is full, the battery charging connection will be disconnected. The software used is Arduino IDE 1.8.1 and X-CTU. The data that can be measured by the tool is the level of air pollution of CO and LPG gas, air temperature and PM 2.5 particulates in the air. The measurement phase
was tested with samples of gas (CO and LPG) as well as a heat source and a cold source for temperature. The test data shows that all sensors are able to detect the presence of CO and LPG gas, temperature differences and dust levels in the air and then display the data in real time.
