Ultrasonic Voice Alert
Difficulty
Security & Surveillance
Summary
Build a simple alert for when people get too close to keep their distance and wash their hands. As the ultrasonic sensor detects the person getting too close, it will use the record and playback module to playback a pre-recorded message. Use it to remind people to wash their hands or as an alert to keep them at a distance.
