Abstract


The objective of this article is to describe the construction and operation of an emergency warnings prototype on dangerous situations. The device sends a predefined message to Telegram, containing the address and a message: -Emergency Alert Activated. The prototype contains a bluetooth low energy (BLE) tracker that detects the proximity of one or more people using any bluetooth device that was previously registered on the system. The MQTT server registers each event every time that the button is pressed. The economic energy mode is deactivated when the button is pressed and soon after sending the emergency warning, it returns to deep sleep mode. The system was implemented in a low cost microcontroller, the ESP32.
