Winsen ZH03A

From low-cost sensors to high-quality data: A summary of ...

The main benefit of low-cost PM sensors is apparent from the name; these instruments are relatively inexpensive. Most PM LCS cost on the order of US$10 to 100 for a single sensor, though the associated electronics and packaging can push costs to anywhere from $200 to $2000 – still a small fraction of the cost of traditional reference PM monitors ().

The least square and RMA correlation of the evaluated PM sensors demonstrated the best linearity achieved at a low PM measurement range (0–400 µg m –3 ). As the Winsen ZH03A and Novafitness SDS011 sensors had coefficients of variation below 10%, both of the sensors have an acceptable precision according to the EPA standard.
