LPU Scientists develop IoT Device to ensure People wash hands for 20 Seconds

Phagwara, July 4(UNI) Researchers from LPU, India’s largest private university on Saturday announced that they have developed 20Sec4Life, an IoT device to time hand washing, that will glow, beep and play a musical tone for 20 seconds to ensure people disinfect their hands properly. It can be mounted on any liquid soap dispenser to ensure the user washes their hands properly as per the WHO guidelines for COVID 19. The splash proof device operates via battery and has been developed to combat the growing cases of COVID 19, which in many cases spreads due to negligence in observing the 20 seconds hand wash rule.
The base device is triggered and starts playing music for 20+ seconds when the nozzle of the handwash is pressed to dispense soap. The advanced version of the device can be connected via Wi-Fi network and can be paired and operated through a Mobile App.
The research team has developed the device prototypes which are available in four variants: 20Sec Musico, a basic model that plays a pre-fed musical tone; 20Sec Glowy, glows for 20+ seconds; 20Sec Beeper, beeps in beginning and would beep after 20 seconds and 20Sec Guardian, an advanced model that offers step by step hand-washing instructions like rub palms, rub fingers on palms etc. in vernacular languages ensuring proper cleaning. The expected selling price of the base model post commercialisation is expected to be Rs 70 per unit.
