Wouldn't air-pollution-sensor be somewhat more generic? At least
wikipedia has some article about that. Various other names like
particle-sensor, pm-sensor, particulate-matter-sensor,
air-quality-sensor, tend to return more or less similar number
of search hits. Which means there's no universal naming convention.
