Class 11 Delhi boy develops touchfree doorbell in times of Corona virus

This wonderful news comes to us from Delhi, India.

In order to prevent the spread of Corona virus (COVID-19), a 16 year old Delhi schoolboy has developed a touch free and automated doorbell keeping in mind the current norms of social distancing.

Sarthak Jain studies in the Modern Public School Shalimar Bagh New Delhi in Class 11 and he designed the doorbell in order to break the chain of the deadly coronavirus. Jain says that it is an automated doorbell equipped with ultrasonic sensors in order to make it touch free.

The sensor is able to detect the presence of an object or a person within 30 to 50 centimeters and it can also produce the “Beep” sound from the buzzer without even touching the doorbell.

Jain says, “I programmed Arduino such that when the ultrasonic sensor will detect the presence of an individual within the range of 50 cm, it will respond by producing a buzzer sound.” He further adds, “Amidst Corona pandemic, I see everyone wearing a mask even while they are in home or balconies. This compelled me to contemplate on all possible ways that this virus could be brought to my home. It struck me that even a doorbell can be one of the potential carriers. So I decided to design a smart doorbell.”

The 16 year old boy reasons that the doorbell remains a susceptible agent of transmission as it is used multiple times a day by multiple persons and hence the chance of spreading the virus remains a big threat. He says that he has designed the doorbell keeping in mind its role in spreading the virus and he hopes that it can be a part of saving the world from COVID-19.

Jain does not forget to thank his school principal Alka Kapoor who had motivated him to design the doorbell. He further adds that his school has an “ATAL TINKERING LAB” where it gives students ample room to explore and delve into scientific principles and applications.”
