 * This Example sends hardcoded data to Ubidots using an ESP32-DevKitC. The code sends a distance 
 * value between an ultrasonic sensor and on the surface of the water detected by an MB7389 
 * HRXL-MaxSonar-WRMT sensor. Then, the value will be managed in Ubidots to calculate the volume 
 * of free-flowing substances in the tank.
