SDS011 (Laser Dust/Air Quality Sensor Module)

Description:

SDS011 is a professional laser dust sensor. Fan mounted on sensor automatically sucks air. Sensor uses laser light scattering principle to measure value of dust particles suspended in the air. Sensor provides high precision and reliable readings of PM2.5 and PM10 values. Any change in environment can be observed almost instantaneously – short respond time below 10 seconds. Sensor in standard mode reports reading with 1 second interval.

There are two ways to communicate with SDS011 sensor:

• digital out (UART)
• PWM signal (one for PM2.5 and one for PM10)

• SDS011 sensor
• cable
• USB-UART converter
