This IoT device can help you clean your hands the right way

Researchers have developed an Internet of things (IoT) device for soap dispensers which they say can ensure that people wash their hands properly for over 20 seconds as per the World Health Organization guidelines for COVID-19.

The base device is triggered and starts playing music for over 20 seconds when the nozzle of the handwash is pressed to dispense soap. The advanced version can be connected via Wi-Fi network and operated through a mobile app. The expected selling price of the base model is expected to be Rs. 70.
