Smart Citizen Opens Eyes And Ears In Barcelona

More often than not, our coverage of projects here at Hackaday tends to be one-off sort of thing. We find something interesting, write it up for our beloved readers, and keep it moving. There’s an unending world of hacks and creations out there, and not a lot of time to cover them all. Still, it’s nice when we occasionally see a project we’ve previously covered “out in the wild” so to speak. A reminder that, while a project’s time on the Hackaday front page might be fleeting, their journey is far from finished.

A perfect example can be found in a recent article posted by the BBC about the battle with noise in Barcelona’s Plaza del Sol. The Plaza is a popular meeting place for tourists and residents alike, with loud parties continuing into the middle of the night, those with homes overlooking the Plaza were struggling to sleep. But to get any changes made, they needed a way to prove to the city council that the noise was beyond reasonable levels.

Enter the Smart Citizen, an open source Arduino-compatible sensor platform developed by Fab Lab Barcelona. We originally covered the Smart Citizen board back in 2013, right after it ran a successful funding campaign on Kickstarter. Armed with the data collected by Smart Citizen sensors deployed around the Plaza, the council has enacted measures to try to quiet things down before midnight.

Today people tend to approach crowdfunded projects with a healthy dose of apprehension, so it’s nice to see validation that they aren’t all flash in the pan ideas. Some of them really do end up making a positive impact, years after the campaign ends.

Of course, we can’t talk about distributed environmental monitoring without mentioning the fantastic work of [Radu Motisan], who’s made it his mission to put advanced sensors in the hands of citizen scientists.

Smart Citizen: Arduino-compatible And Packed With Sensors

smartCitizenBoard

If you’re going to develop another Arduino-compatible board these days, you might as well take a “kitchen sink” approach. The Smart Citizen Kit piles it on, including Wi-Fi, an SD card slot, and EEPROM on its base. The attached shield—dubbed the “Ambient Board”—is a buffet of sensors: temperature, humidity, CO, NO2, light intensity, and a microphone for reading sound levels. The board’s intended purpose is to provide an open-source, interactive, environmental database by crowdsourcing data from multiple Smart Citizen Kits, but you can add your own stuff or yank the shield off altogether. Additional shields are also under development, aimed at providing agricultural data, monitoring biometrics, and more.

Stick the Smart Citizen somewhere and it can send sensor data to the web over a WiFi connection. The result is worth a look. Here’s the map with the real-time data from early release models scattered over Europe, most of which appear to be solar-powered with a small LiPo battery to keep them going overnight. There’s also an accompanying iPhone app that lets you set up the Smart Citizen, retrieve data from nearby sensors, and allows you to match your phone’s GPS location to any data you collect while carrying the board around.

The developers met their Kickstarter goals earlier this summer and the board has recently entered the manufacturing process, Rummage through their GitHub files here, and watch a video preview of the Smart Citizen below.
