ESP8266 volumeter

This ESP8266-based IoT volumeter measures the volume of an open space inside an enclosure using ultrasonic sensors. Three HC-SR04 ultrasonic transceivers are placed orthogonally to measure distances (width, height and lenght) along the three directions to compute the volume. The measurements are sent to the CloudMQTT server and displayed as graph.
