Abstract
A physical prototype of a universal gas analyzer has been presented for online measuring the concentration of several gases (methane, propane, butane, carbon monoxide, hydrogen). Software for an Android smartphone has also been developed in order to perform the visualization and management of data received from the gas analyzer. The smartphone is used to display information, to control the modes of displaying information on the screen, to determine the location of the user of the gas analyzer, and to send operational information to a remote server. At the moment, we can visually observe changes in the concentration of detected gases, view the measurement locations on maps, and manage the program in a convenient interface. The proposed prototype has compact controls, a built-in power supply, which facilitates the operation of the device. The Central computing part of the device is an ATmega 328P microcontroller, which is chosen due to its availability, versatility, and the ability to reprogram the outputs. The design of the device provides a connector for easy reprogramming. The measuring functionality of the device is determined by a set of sensors connected to the microcontroller, and does not depend on the smartphone model. Each sensor can be replaced owing to the modularity principle. The proposed device is compact, durable, easy to use, has an ergonomic design, performs real-time measurements, has various monitoring capabilities, and can be used for industrial and domestic purposes to control hazards directly at the location of a person.
