Air Pollution Detection Information System in The East Jakarta Industrial Environment Using Internet of Things Based Geography Information System Technology

Technology is currently developing so rapidly, almost all activities of human life cannot be separated from the use of technology. With increasing technological developments, this can certainly be used to overcome air pollution problems. The system limitations that will be designed are a pollution detection system using the MQ2 and Telegram sensors based on the NodeMCU ESP8266. The detection system that will be implemented consists of installing MQ2 sensors, buzzers, LEDs and LCDs as well as a Telegram application to provide notifications. Based on the results of analysis and testing of pollution detection system tools using the MQ2 sensor and Telegram based on NodeMCU ESP8266, it can be concluded that the sensor will detect smoke around the sensor. If the smoke detected is more than 100 PPM, Telegram will send a warning notification along with the buzzer and LED lights. However, if the detected value is less than 100, Telegram will not send a notification and the buzzer and LED will not light up.
