Laser Dust and Particle Sensor, SDS018 0.3 to 10micron

Description

What it is

The SDS018 laser sensor is a device for measuring the concentration of dust and particles in the air, useful for environmental monitoring projects. It measures air particles from 0.3 to 10 microns.

Features

• Measures air particles from 0.3 to 10 microns
• Ideally suited for monitoring air quality in indoor environments such as homes and offices

What it is for

The SDS018 sensor can be used to build simple air monitoring devices that send dust and particle data to online platforms. It is compatible with Arduino and ESP.

Tutorial: How to Use Laser Sensor SDS018

The SDS018 sensor is a device for measuring the concentration of dust and particles in the air. Ideal for environmental monitoring projects and respiratory safety devices.

What you need

• Arduino Uno or compatible
• USB cable
• Internet connection
• Adafruit_Sensor library

Steps

1. Connect the SDS018 sensor to digital pins 2 and 3 of the Arduino
2. Install the Adafruit_Sensor library through the Arduino IDE library manager
3. Load the example sketch provided by the library
4. Verify sensor communication with the Arduino serial monitor
5. Calculate particle concentration based on received data

Example code
