Concept

Privacy Conscious

Real-time Monitoring

Easy to set up

Wi-Monitor is a brand new system to measure occupancy of areas. It uses only Wi-Fi to recognize the number of people in the room. The number of people can be checked online.

Now camera is widely used to detect congestion, which is questioned for its invasion of privacy. Wi-Monitor is a privacy conscious system. It only uses the amount of change of Wi-Fi signals between transmitter and receiver.

Wi-Monitor can easily show the number of people in the room to real time, while camera needs huge amount of computing resource to do so.

You only need to stick this on the wall to measure the occupancy. Wi-Monitor is a small device. it is 6 × 3 × 2 cm . It sends data to cloud, and the results are shown on webpage.
*You need to teach it the number of people for about 30 minutes.

Advantages

Camera

Need to place where the whole area can see.

Useless under dim lights

Beacon

Expensive

Measure only those who have smartphones

Wi-Fi

Ours

Privacy conscious

Real-time monitoring with normal computing resources.

Method

Wi-Fi have a property of reflecting on water. Water makes up 80% of human body. This leads to the fact that human body reflects Wi-Fi. Therefore, by linking the amount of change in Wi-Fi signals between transmitter and receiver and the number of people through machine learning, you can detect the number of people.
