Dust/air quality sensor PM1.0 / PM2.5 / PM10 - PMS5003 - 5V UART
 
You can track and sense the quality of the air around you with the PM2.5 Air Quality Sensor - particulate sensor.
PM2.5 refers to particles that are 2.5 microns or smaller in diameter.
This sensor uses laser scattering to radiate suspending particles in the air, then collects scattering light to obtain the curve of scattering light change with time.
The microprocessor calculates equivalent particle diameter and the number of particles with different diameter per unit volume.
PM1.0, PM2.5 and PM10.0 concentration in both standard & enviromental units
Particulate matter per 0.1L air, categorized into 0.3um, 0.5um, 1.0um, 2.5um, 5.0um and 10um size bins
 
Description
The PM2.5 Air Quality Sensor (PMS5003) functions as a digital and universal particle concentration sensor. It accurately measures the number of suspended particles in the air, known as particle concentration, and outputs this data through a digital interface. Users can integrate this sensor into various instruments or environmental improvement equipment to promptly obtain accurate concentration data.
This advanced sensor module provides accurate real-time measurements of particulate matter (PM) concentrations in the air, helping you to assess and monitor indoor and outdoor air quality.

Please Note:
For outdoor applications, a vented enclosure undercover is recommended to protect the sensor from the elements.
The TTL logic level for this sensor is 3.3V. If your microcontroller uses a logic level greater than 3.3V, you will need to use a logic level shifting module.
