Sistema de sensoriamento sem fio aplicavel a deteccao de incendios florestais

In this research work, a hardware and software system is developed that uses wireless sensors to monitor environmental variables such as temperature, gas concentration and luminosity, in order to detect the existence of forest fires. Lora technology was used for wireless sensor networks with communication range that can reach on average up to 5km in urban areas and 10km in rural areas. The developed system also has an integrated web application (dashboard) and that in real time, collects data from wireless sensors, which together form the sensor module, also called device. Then, this data is presented on a map associated with the positioning of each sensor module. The developed system was tested using practical experiments that used flames, gases and lighting, simulating the occurrence of fires. With the tests performed, it was observed the feasibility of the system, hardware/software developed, in detecting the fires in the simulated scenarios. Therefore, it was found that the research is promising, and may advance in the future for the detection of real fires.
