There is an interesting new sensor model on the market - Panasonic SN-GCJA5  
Technical information:  
[https://na.industrial.panasonic.com/products/sensors/air-quality-gas-flow-sensors/lineup/laser-type-pm-sensor/series/123557/model/123559](https://na.industrial.panasonic.com/products/sensors/air-quality-gas-flow-sensors/lineup/laser-type-pm-sensor/series/123557/model/123559)

Much smaller than the SDS011 - a quarter of the size.  
About the the same price as SDS011.

Maybe it would be worthwhile to implement this sensor?

Great! Panasonic / Matsushita is a good brand.  
Maybe they can send me one. Or I will try to get a letter in Japanese.

By the look at the datasheet I am afraid this sensor may be not very precise and accurate below 35µg/m³.
