* 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. | |
* | |
* This example is given AS IT IS without any warranty. | |

* Made by María Carlina Hernandez. | |
