Sensors & IoT

539 documented projects · Explore all 539 Sensors & IoT projects →

Sensors & IoT is the single most common tag in this entire dataset — more projects carry it than any other topic, "AI" included. That's not surprising once you notice that almost every other tag (traffic, air quality, flood, waste) describes a problem, while this one describes the instrument most of those problems get solved with.

The research testbeds that started it

Santander's SmartSantander, an EU-funded testbed running 2010-2013, federated more than 20,000 sensors across four European cities, with 12,000+ deployed under Santander's own streets and lampposts — one of the earliest attempts to find out what city-scale sensing was actually good for, before "smart city" was a marketing term. Chicago's Array of Things took the same instinct public a few years later: 100+ modular nodes on lampposts measuring air quality, noise and pedestrian flow as fully open data, self-described as "a fitness tracker for the city."

Sensors as infrastructure for something else

Egypt's New Administrative Capital shows what happens when sensor infrastructure is built in from the start rather than retrofitted: a Honeywell-built system links 6,000+ CCTV cameras to a central command centre, with smart columns every 250 metres carrying additional sensing — infrastructure poured into the ground alongside the roads themselves, for a city built for 6.5-7 million residents from scratch.

When the sensors overreach

San Diego's US$30 million CityIQ network — 3,000+ streetlight nodes with cameras, microphones and environmental sensors — was deactivated in September 2020 after the ACLU raised concerns about police access to the footage it had quietly been collecting; it only returned in 2023, under a narrower five-year agreement covering 500 cameras with new operators. It's included here on purpose: a sensor network's technical spec sheet rarely mentions who else can query it later, and that question is often what determines whether a deployment survives in any form.

What ties these together

From a research testbed to a purpose-built capital city to a streetlight network that had to earn its way back after a shutdown, the pattern is the same: sensors are cheap to install and hard to govern well. See the Data & IoT category for how these sensor layers feed into open-data platforms and digital twins.
