Abstract: Recently, there have been many developments in the area of gas detection. In this article, we design a compact wearable gas detector. The designed gas detector is implemented using ATTINY85 microcontroller, a gas sensor and the OLED display. The MQ-4 gas sensor senses methane, propane and butane which are the main constituents of natural gas. To notify the gas concentration to the user an OLED display is used. When the gas concentration reaches the specified threshold the user is notified by an alert message in the OLED display. The gas detector designed is smaller and cheaper and can be used in household, mining sector and industry.
