The Smart Citizen Kit (SCK) is a bottom-up environmental sensing platform. It enables citizens to become active in capturing, sharing and making sense of data on the local environment, through the use of low-cost sensors. An ongoing project, the kit measures the levels of Carbon Monoxide (CO), Nitrogen Oxide (NO2), temperature, humidity, light and sound in the city of Manchester.

It was inspired by the vision that citizens can be active in the operation and invention of the city, and active custodians of the environment. Manchester is the third city, with Amsterdam and Barcelona, to establish a local Smart Citizen community engaged in bottom-up sensors and sensing. The Smart Citizen Manchester community both helped shape the evolution of the platform in Manchester, and look for applications of the data to improve air quality and wellbeing in the city.

Connecting data, people and knowledge, the objectives of Smart Citizen is to serve as a node for building productive open indicators and distributed tools, and thereafter the collective construction of the city for its own inhabitants.

Smart Citizen is based on open platforms for data collection and sharing, comprising of the Smart Citizen Kit itself, RESTful API, a mobile app and web interface. At the heart of the kit, which is around the size of a pack of cards, is the ‘Ambient Board’, a piece of hardware comprising of two printed circuit boards: an interchangeable daughterboard, or ‘shield’, and an Arduino-compatible data processing board.
