Multifunctional Wireless Push Button Based on LoRa Technology

This research project develops a multifunctional push button device using LoRa technology, providing a reliable and energy efficient solution to manage wireless networks in areas without Internet access. The device has compact dimensions of 50 x 50 x 13 mm3 and integrates a LoRaWAN module. Its antenna features a resonant frequency of approximately 0.923 GHz, with bandwidths of 20 MHz and 11 MHz for -6 dB and -10 dB, respectively. Using the OTII ARC Power Analyzer, the device achieves a minimum current consumption of 8.2 μ$A$, ensuring a long operational lifespan. Furthermore, the push button was tested both indoors and outdoors, showing a maximum packet loss of 7.89 % and 1.33 %, respectively. These results demonstrate the effectiveness of the device in various environments.
