Chicago equipped sensors for real-time monitoring of city indicators

Tencent Digital (Compiled: Hamish) Chicago is one of the largest cities in the United States. The city has a unique personality. To better understand the character and temperament of “Feng Cheng”, Charlie Catlett, the head of the Urban Computing and Data Center of Argonne National Laboratory in the United States, came up with an idea: “Why not fill the sensor in this city? To track its every move?"

Last year, Chicago began investing in the construction of new street lights. Through this project, Catlett’s team installed revolutionary sensors on these street lights this week. These sensors are called Array of Things and they will record an unprecedented mark for Chicago.

After the project started, Array of Things is expected to provide data for community groups, local Chicago government, and various companies, bringing together all aspects of Chicago. By recording air temperature, barometric pressure, carbon dioxide, nitrogen dioxide, and light levels, Array of Things will leave researchers with invaluable data.

"I think that better understanding of the climate and air quality will bring tremendous opportunities to the scientific research community," Catlett told Fast Co. Design.

After learning about the transformation of the old streetlight in Chicago, Catlett immediately saw the opportunity to change. He assigned the data collection task to the University of Chicago students and researchers at Argonne National Laboratory, who gave the design of the sensor to Chicago. Art school. After completing its previous work, the National Science Foundation agreed to bear some funding for the development and manufacture of sensors.

With the financial guarantee, Catlett's team began to focus on designing sensors. The design team not only needs to distinguish the Array of Things shape from the surveillance probes, but also needs them to be able to withstand the “schizophrenic” weather in Chicago—the city is cold like a ice cave in winter and very humid and hot in summer. In addition, the design team needs to make the appearance of the sensor look more lovable.

"We don't want to create something that looks very serious, and we don't want sensors to be 'invisible,'" Catlett said. "We want to create an attractive product that will be difficult to see when you see it." Make sure it is a meteorological device or an artwork."

In the final design, Array of Things consists of a blue box with the "Array of Things" logo and a honeycomb shaped sensor. When installing, simply fix it to the traffic light or street light pole. However, an innovative thing will always cause some controversy, especially in terms of privacy policy.

Since Array of Things will monitor traffic flow and pedestrian data, it will use video or photos to record people's every move. Some people are dissatisfied with this. Although the sensor's privacy policy has stated that images and other data will only be used for short-term analysis, it will still retain some image data for later reading.

In this regard, Chicago City’s chief information officer Brenna Berman believes that Array of Things is a product that outweighs disadvantages. The data it receives will help the government make better decisions. Berman said: “This will be a key step in our transition to a data-driven government. It gives us more data to make decisions and allows us to serve the public better and more efficiently. Chicago has 30,000 government employees, 300 Ten thousand partners use the data to make the city better."

At present, Array of Things is in its infancy, and whether the data detected by the system has actual utility remains to be observed. To date, 42 sensors have been installed throughout the city. Catlett’s team hopes to expand this number to 60 to 80 before the winter arrives.
