Tools of Atmy air quality
	Description		Read-only	Idempotent	Open world
`find_sensors`Single sensors with their latest reading (PM1, PM2.5, PM10, temperature, humidity, pressure), network and quality check: status, rating 0–10 of the last checked day, the mean rating of the last 7 days and the reasons. Filter by city, country, or a point with a radius; sort=rating puts the most reliable sensors first.
