Inspiration
What it does
Our human sensor is placed around the door, which can judge whether people come in or get out of the room and display the total number in the room.
How I built it
We use Arduino 101 with, a sonic sensor(Ultrasonic Sensor), a light sensor(Photoresistor) and a motion detector(HC-SR501 PIR Sensor) to build this human sensor.
Challenges I ran into
The main challenge is that all members of our team do not have any experience of how to use Arduino. The second challenge we met is where to put our sensors. We used the ultrasonic sensor to detect the position of the door, the motion sensor to determine if there is a person near the door and the photoresistor to determine which direction the person is moving.
Accomplishments that I'm proud of
Our display was not working and I fixed it.
What I learned
We learned lots of knowledge about Arduino and how to set up for digit display.
What's next for Human Sensor
For the future, we need to improve the sensitivity of our sensors. What's more, we can set up our database to store the number of people in that room during each time of the day. Using this database to predict how many people will in the room at a specific time.
