Grove - Particulate matter sensor (PPD42NS) - PM 2.5, dual PWM output

Grove - Dust sensor (PPD42NS) - measures PM 2.5, dual PWM output

This dust sensor provides a good indication of the air quality in an environment by measuring the dust concentration. The level of particulate matter (PM) in the air is measured by counting the Low Pulse Occupancy Time (LPO time) in a given unit of time. The LPO time is proportional to the PM concentration. This sensor can provide reliable data for air purification systems. It responds to PM with a diameter of 1 μm. 

Application:

• Air purifier
• Air quality monitor
• Air conditioner
• Ventilator

Features:

• Wide measurement range: detect not only cigarette smoke but also indoor dust (an asthma trigger)
• Stable and sensitive measurements: dual PWM output for particle sizes above 1 micrometer and 2.5 micrometers (approx.)
• Long-term use: air intake by the flow of the air generation mechanism with built-in heater, easy to maintain
• Compact and lightweight design: compact size facilitates installation
• Easy to operate: Compatible with Grove port, easy plug-and-play
• compatible with Arduino and Raspberry Pi

What is Grove?

Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. 

We offer various Grove shields to enable a connection to the Grove system with various microcontrollers. 

Scope of delivery:

• 1x Grove dust sensor (PPD42NS)
• 1x Grove cable
