I’d like to expand on my sound crit idea to incorporate the invisible factors around covid prevention. Three sensors I’d use – wind sensor, ultrasonic sensor, volume sensor. Together, they can provide the count on the number of people in a room, ventilation speed and how loud people are talking. This would feed information into a p5.js sketch that shows a visualization of what’s in a green, orange or red zone. This can also be accompanied by a sound when the red zone is reached, and potentially windows can be set to open automatically.
Alternatively, I could also work on a shopping mall entrance checker with a temperature sensor and a ml5.js sketch that recognizes whether the person in front of it is wearing a mask. If they’re not wearing a mask, the door doesn’t open to allow them to enter (probably use a servo to simulate this), even if their temperature is within range.
