The SDS 011 Sensor
With its size, it is probably one of the best sensor in terms of accuracy: While other sensors tend to focus on shrinking the sensor size, the SDS 011 has opted for a size tradeoff allowing it to use a larger fan. And the larger the fan, the better the quality.
Specifications
This is the specification for the SDS011. One should not consider all those values for granted as there is quite often a big difference between what is said to be possible and what is actually possible (and this is why we are setting up all our experiments).
