Desarrollo de un prototipo IOT para la localización de descargas atmosféricas mediante la triangulación de sensores.

Abstract

The objective of this Curricular Integration Work was to develop an IoT prototype for the location of atmospheric discharges (lightning) through the triangulation of sensors. The multi-station method, the SPI, Wi-Fi, TCP, HTTP protocols, the AS3935 sensor and the ThingSpeak platform were used. Next, the IoT prototype was developed for the location of the lightning strike point in the province of Chimborazo based on the following steps: 1) location of the study area to perform the triangulation; 2) interconnection of the ESP32, DHT22 and AS3935 components; 3) ThingSpeak platform configuration; 4) development card programming; and, 5) storage and processing of data on the server to calculate the lightning strike point with its respective coordinates, thus creating a script with the lightning visualization in Google Earth. Next, the results obtained on January 31, 2023 correspond to three lightning strike events; such as: First, located at the coordinates of longitude -78.7444 and latitude -1.17429; second, located at the coordinates of longitude -78.7276 and latitude -1.7341; and third, located at the coordinates of longitude -78.6908 and latitude -1.7247. Finally, it was concluded that these three events indicate the direction in which the electrical storm propagates; specifically, it was directed towards the south of Riobamba and it was recommended to separate the AS3935 sensor from any device that produces signals close to 500 KHz - 2 MHz at a minimum distance of 10 cm, in order to avoid interferences that impair detection efficiency.
