  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.
