Royal Grammar School Newcastle – Years 7-9
To help minimise the spread of COVID-19 and other viruses, we have developed a visor that automatically lowers when you’re within two metres of another person.
Our prototype consists of a visor attached to a helmet that houses an ultrasonic distancing sensor, servo, buzzer and battery. We have programmed the ultrasonic sensor to activate the servo and lower the visor whenever you are within two meters of someone. The buzzer also makes a noise when you get within two metres of someone to encourage social distancing.
Our visor has several advantages over the masks we have all gotten used to. It’s more comfortable. It doesn’t restrict breathing, meaning more people can use it. And it automatically activates when you need it most.
We didn’t end up using the buzzer, as we had to work from home, which caused us to have significantly less time to make our distancing sensor. If we had used the buzzer, it would have made a noise signalling that you were too close to another person.
