Resum

There is a great need nowadays to monitor environmental parameters for safety and moreover for fire safety. Thousands and millions of deaths due to catastrophes produced by fire can be avoided by using smart communications systems. In addition, the born of the new IoT era where almost every physical magnitude can be monitored in the cloud makes more plausible the necessity of using IoT wireless devices under different communication protocols. One of the most modern ones with best characteristics in terms of space distance and low energy consumption is the Long Range Wide Area Network (LoRaWAN) protocol that is able to transmit packages at distances from the emitter further than 10 km in interurban areas in open air. In this work, we present two different applications of smart fire-safe long-range communications systems: one is an alarm system that uses fire resistant triboelectric nanogenerators (TENGS) to trigger a signal of advice. The other one is a fire resistant vibration sensor able to monitor seismic waves in 3D axis at high temperature such as inside a volcano and to very long distances by using 868 MHz LoRaWAN communications protocol. Both will allow preventing many forests from extinction when high ground motions under the presence of fire are detected.
