Low-cost sensors, honest about what they can and cannot show
What the sensors do
Measure particulates continuously at fourteen points. Accurate enough for trends and comparisons, not for legal thresholds.
What we do with it
Publish it, all of it, including the readings that are boring. Selective publication would destroy any credibility the project has.
What is needed
Fourteen householders willing to host a sensor on an outside wall with a plug socket nearby. Electricity costs about four pounds a year.
