Grove - Dust Sensor（PPD42NS）

This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration.

Features

• Wide measurement range: Not only cigarette smoke, but also indoor dust, an asthma trigger, can be detected.

• Stable and sensitive measurements: dual PWM output for particle sizes over 1 micron and 2.5 microns (approx.)

• Long-term use: Air is self-priming through the current of the air generating mechanism with built-in heater, easy to maintain

• Compact and light design, easy to install

• Easy to use: compatible with Grove port, just plug-and-play

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 with guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product.

Note

This sensor uses a counting method to measure dust concentration, not the weighing method, and the unit is pcs/L or pcs/0.01cf.
