Story

Sandisp! is an automatic sanitizer dispenser with voice notifications based on Arduino nano and infrared proximity detection.

Once proximity is detected by the system, You will hear the voice notification from the device, it tells you what to do next. And finally dispenses the alcohol-based sanitizer.

Features
  • Voice notification can be created in 100+languages.
  • High sensitive proximity detection up to 1 meter.
  • Lm567 Based PWM based proximity detection works in bright sunlight.
  • Open-source: source code and Hardware design files are available for download.
