Each series, we dedicate an episode to looking behind the scenes of data. In this episode, we showcase the work of the data journalism project, Sensemaker.

For the project, the Manchester Evening News partnered with the University of Central Lancashire to co-create data sensors for journalism and community engagement.

One of these was a pollution sensor, which was deployed in schools and businesses across South Manchester.

Annie Gouk spoke to John Mills, Associate Professor at UCLan and one of the academic partners on the Sensemaker project, and Louise Taylor, who was the assistant headteacher at Cringle Brook school at the time.

Hosted by Annie Gouk and produced by Mark Magill.
