20 Crowd Monitoring Device

Theme parks, airports, hotels, libraries, corporations, etc., all have general ideas of how many people are on their premises throughout the day or year but they do not know the instantaneous count of people over that area.

Our solution for accurately counting individuals entering or exiting an area is a portable device which can be mounted above a door frame. It will consist of several components:

-Mixed sensor module--Passive infrared sensors for detecting a human being about to cross a doorway and trigger ultrasonic sensors
--Ultrasonic sensors for detecting the heights of individuals, whether they are entering or exiting, and determining whether multiple people are crossing the threshold simultaneously
---We will use different frequency ultrasonic sensors focused at different angles to gain topology information at different locations simultaneously
---We will trigger sensors successively to gain topology information at given locations at different times
--Possible infrared camera to better detect boundaries between humans

-Processing module
--Internal microcontroller for A/D conversion and initial signal processing
--External server for advanced signal processing

-Communications module
--Bluetooth or Zigbee to send data from microcontroller to external server

-Power module
--Converts standard outlet power to required sensor, microcontroller, communications module demands

The project is appropriate for senior design because we are dealing with power distribution, communication protocols, and signal processing.

SensorInsight currently provides a camera-based solution for watching crowds flows over a wide area. Our solution is different because we focus on precisely counting people entering or exiting an area. We seek to build a much cheaper solution than one of SensorInisght’s high definition cameras with our mixed sensor module.

LED Cube

LED Cube

Featured Project

LED technology is more advanced and much more efficient than traditional incandescent light bulbs and as such our team decided we wanted to build a device related to LEDs. An LED cube is inherently aesthetically pleasing and ours will be capable of displaying 3D animations and lighting patterns with much increased complexity compared to any 2D display of comparable resolution. Environmental interaction will also be able to control the various lighting effects on the cube. Although our plan is for a visually pleasing cube, our implementation can easily be adapted for more practical applications such as displaying 3D models.
