An environment becomes knowable through the distribution of capacities to sense it. Jennifer Gabrys displaces environmental knowledge from a privileged observing subject toward arrangements in which devices, bodies, infrastructures, communities and landscapes participate in making conditions perceptible. Smart-city sensing reorganises governance: it programs feedback loops and assigns technical roles to urban actors, and measurement follows from that reorganisation.
Citizen sensing generates data practices through which residents formulate environmental concerns, narrate exposure and contest the terms by which regulatory knowledge is recognised. The concept of "just good enough data" fixes this point: data acquire epistemic significance relative to the problems, publics and actions they enable. "Sensors Experiencing Environments" extends the argument. Sensing technologies participate in composing computational environments, and experience distributes across technical and more-than-human relations.
