And if music is still playing during the timer countdown, washing your hands also puts you in a good mood.

Soap dispenser from the drugstore We use a battery operated soap dispenser which is suitable for 6, 99 € (with batteries and 250 ml of soap) under the Name Sagrotan No Touch is available in drug stores. There are several versions with different soap scents as well as a special kids edition, but they are all identical.

The soap dispenser already has appropriate sensors to be able to remove soap without contact. We use this instead of the proximity sensor module described in the article “Hand washing timer with contactless switch”, so that the hand washing timer starts automatically as soon as soap is removed. We also use an MP3 player module, which is also controlled by the sensor and plays music.
