The project records voice signal from the road and send the data to a nearby control station. The control station creates the voice file and analyzes it in order to determine whether there is a crack or sinkhole in the road.
There is a necessity to find cracks and sinkholes at an early stage.
An early solution was to find cracks and sinkholes using vibrations of the road. The device was big and heavy and needed to be buried underground.
This solution detects cracks and sinkholes by “listening” to the road and send the data using Wi-Fi to a nearby control station. The device is compact, independent and power efficient and can be placed on any road without interference.
The Goal was to Design, Construct and Program a device that samples voice, at a predefined time at day, for a short period of time. The device sends the voice sample to a nearby control station that analyzes it and determines whether there is a crack or a sinkhole in the road.
The project is based on Arduino Open-Source Platform. The Arduino gets analog data from the mic and write it to the SD-Card at a certain time of day. The Arduino is connected to ESP8266 IOT device programmed using Arduino IDE. The ESP transmSits the data via Wi-Fi to a nearby control station that creates the sound file and analyzes it.
