| Popis: | This work presents the use of the Internet of things (IoT) applied to a control of an actuator that works through temperature and approximation values. The proposed technology consists of three principal parts: Hardware (Raspberry Pi 3), a virtual machine installed in “the cloud” and a mobile device with a Global Positioning System (GPS) application. A system was developed in the Raspberry Pi 3 that is connected to a temperature sensor which monitors the external temperature and is connected to a mechanical actuator. This part of the system is able to send a message to the cloud concerning the ambient temperature which is stored on a database. The mobile device consists of an Android application based on GPS positions which is able to send a positional message to the cloud that is stored on a database. A cloud development records the latest position and temperature data which are then compared to a predetermined threshold value in development. Through the logical operation AND between the comparisons of the temperature and position values with the threshold values, the decision to switch the actuator on or off is taken. The system performs the storage and comparison of the cloud data each time interval t predetermined in the development. The proposed system was validated through a case study. |
