Diseño de dispositivo de bajo consumo para la lectura de gases dentro de una galería

Abstract

The project consists of the design of a measurement system, autonomous and low consumption to measure gases, temperature and humidity inside a gallery. The scope of the project has been directed to be able to know how the gases vary inside the galleries, to increase the security of employees and to reduce costs when opening the gallery. Firstly, it has been established as minimum goals fulfil with the client requirements and overcome them. Secondly, a component selection process has been carried out for the design of the device, making a study of the market and the needs of the device. Thirdly, a cyclical system has been chosen which consists of reading the measurements from the sensors, processing the data and adapting it to information of interest to the user and sending it to a removable memory card in easy to work files. Then, the device goes into power down mode until the new measurement. Finally, the device’s PCB has been designed and a way of encapsulating it has been proposed to ensure the protection of the measurement system.
