Sistem Pemantauan Debu Secara Real-Time Pada Daerah Pertambangan Batu Bara

Bunyu Island is one of the districts in Bulungan Regency and has abundant natural resources, thus making it much ogled by large mining companies to extract process these resources. However, may change air quality around area be poor. This research developed a device that had an electronic sensor as input device, NodeMCU ESP8266 microcontroller Blynk Application viewer output device. was carried out two stages testing, namely GP2Y1010AU0F software. In done testing tool error continuing test voltage using 3 samples form smoke, paper ash, dust against density. test, result were nit too large, 1.43% 1.67% value, stress different results obtained sample according density each sample. While at stage software, indoors outdoors. software good where application displayed notification when read above threshold.
