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.

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
