PRODUCT DETAILS

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: Compact size makes installation easier
Easy to use: Compatible with Grove port, just plug-and-play

Description

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.

What is Grove？

We have developed more than 400 Grove modules, covering a wide range of applications that can fulfil various needs. Click to explore the Grove Sensor family [ https://wiki.seeedstudio.com/Sensor/ ] and get started to Grove your Idea. For all Grove users (especially beginners), we provide you with guidance PDF documents. Please download and read through Preface - Getting Started [ https://www.seeedstudio.com/document/pdf/Preface.pdf ] and Introduction to Grove [ https://www.seeedstudio.com/document/pdf/Introduction%20to%20Grove.pdf ] 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.

Please pay attention to the warnings listed here [ https://wiki.seeedstudio.com/Grove-Dust_Sensor/#jump ] .
