Description
Summary:In the development of science and technology in the electronics field. So it can provide inspiration in the development of measuring instruments for the measurement of SO2 Particulates and Gas which provide economic and efficient value, so that it can be used by the public in measuring SO2 Particulates and Gas levels in the Sidoarjo Mudflow area. The Android-based measurement system on SO2 Particulates and Gas is an implementation of previous developments in terms of data display visible on smartphones and can be accessed remotely or anywhere connected to Wi-Fi or the internet network. So that it can easily take data in the measurement of SO2 Particulates and Gas. The design of this tool consists of ESP32 NodeMCU as a microcontroller, Particulate (Dust) sensor and MQ136 (SO2) sensor. Wi-Fi network or internet to facilitate communication between sensors and smartphones. The test results obtained a value of 0.104 (mG/Nm3) from the Particulate sensor with the category still at a safe level when compared to quality standards, and 15 ppm for SO2 Gas detected around the Sidoarjo Hot Mud. This shows that the sensor is working optimally and is very sensitive at the reading level.
