I am doing a project that entails a user to physically wear a microwave proximity sensor in the form of a bracelet in the hopes to detect when another person comes in contact of 2-3m. This would be used in our situation now of COVID-19, to allow people to accurately social distance.
My question is, is there a way to set a specific distance, say 0.5m-3m within a proximity sensor. As issue's are arising of the wearer being detected themselves and the cap being 3 metres distance.
Do any of you have any suggestions?
