Description
In June 2019 engineers at Duke University in the USA announced they were teaming up with the North Carolina Department of Public Safety to develop an alerting system that uses microphones and thermal cameras to detect unwanted drones and the people flying them, says a Duke University news report. The Raspberry Pi is loaded with a machine learning algorithm that constantly processes the data collected from the microphone to isolate the sounds a drone makes from background noise. When it detects the buzzing whir of a drone’s propellers, it sends a notification to an app loaded on smart phones carried by the prison’s security personnel.
