Abstract

Sensors, in general, are a pillar of contemporary technology. Their applications, types and models are used in several fields. Thus, it becomes indispensable development of sensors and wireless communication methods between devices, even as equipment control. This work proposed a system to detect liquefied petroleum gas (LPG) in a mixture with air, using an experimental apparatus organized by the gas sensor element, a temperature controller and an Arduino board equipped with a Zigbee wireless data transmitter. The work involved the area of chemistry and computing to reach aims, from development of SnO2 sensor element to instrumentation. The text presents the preparation of colloidal suspension, film deposition and thermal treatment, gas mixture system assembly and sensor element heating. Also, was described the microcontroller couplings for data transmission via Zigbee devices, the design and construction of the voltage divider circuit, as well as the characterization of the oxide film and sensor measurements in a gas and LPG atmosphere. A microcomputer, using a program written in Python, stored the data, conditioned by a microcontroller, received through the Zigbee wireless network. In addition to the technical results for the gas sensor developed with sensitivity within the limits of flammability, the work allows to conclude that the involvement of related areas can results in the development complete work from sensor preparation to instrumentation.
