This page was created as part of a bachelor’s thesis by Armin Gembal<\/strong> at VSB \u2013 Technical University of Ostrava, with the topic Design and Assembling of the Communication Node of the LoraWAN technology Operating at 433 MHz Band<\/strong>.<\/p>\n

This project describes the assembly of a battery-powered alarm device operating on a\u00a0LoRaWAN<\/strong>\u00a0network in the\u00a0433 MHz<\/strong>\u00a0frequency band. The key feature of the node is its\u00a0Deep Sleep<\/strong>\u00a0operation mode. The device wakes up only when one of the three connected sensors detects an event. After waking up, the\u00a0ESP32<\/strong>\u00a0sends a single-byte packet to\u00a0TTN<\/strong>\u00a0(The Things Network).\u00a0TTSS<\/strong>\u00a0(The Things Stack Sandbox) then forwards the message via\u00a0Webhook<\/strong>\u00a0to\u00a0GAS<\/strong>\u00a0(Google Apps Script). The script decodes the payload and immediately sends a text notification to a\u00a0Telegram<\/strong>\u00a0chat.<\/p>\n
