The world is struggling with the COVID-19 pandemic and hand disinfection is crucial. The biggest problem with hand sanitizer dispensers is that they are often empty. This smart dispenser checks the level of disinfectant liquid and sends it to Arduino Cloud. The staff can easly check this level on dashboard.
Pouring liquidWhen there is a liquid in container, "READY" is displayed. When you pass your hand in front of the device, the liquid will start to flow out after a while.
Liquid level measurementsThe sensor checks the liquid level every specified period of time (about 0.5s by default). If it is more than 5%, "READY" is displayed. Otherwise, "EMPTY" is displayed and you can't run the pump.
Every 60 seconds (by default) the measured value is sent to the Arduino Cloud. The service staff can check it on the dashboard.
