Grove - Dust Sensor（PPD42NS）
Provide reliable data for air purifier system Easy maintenance PWM output Grove compatible interface Compact and light design
Who Viewed This Also Viewed
This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in a given time unit. LPO time is proportional to PM concentration. This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
Note
This sensor uses a counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf.
Please pay attention to the warnings listed here.

Hi Aldrich~ Unfortunately, this sensor measures the amount of particulate matter, not the weight. So it is nearly impossible to change pcs into grams. Regards
