Fine-Particle Sensor PM2.5 and PM10 SDS011

Description

What it is

The SDS011 fine dust sensor is a device for measuring PM2.5 and PM10 particles in the air, useful for environmental quality monitoring projects with Arduino.

Features

• Measures PM2.5 and PM10 particles
• High precision for air quality monitoring

What it is for

Develop real-time environmental monitoring systems with Arduino by integrating the SDS011 sensor. Use platforms like ThingSpeak or other online solutions to visualize collected data.

Tutorial: How to Use the Fine Dust Sensor SDS011

The SDS011 sensor is a useful device for monitoring air quality, specifically PM2.5 and PM10 particles. This tutorial will guide you in its use for both 3D printing projects and environmental monitoring systems.

What you need

• Arduino Uno or compatible
• USB A-MicroB cable
• SDS011 Fine Dust Sensor

Steps

1. Connect the SDS011 sensor to the Arduino using a TX-RX cable and GND-VCC.
2. Download the SDS011 library from GitHub or the product page.
3. Insert the provided Arduino code in this tutorial.
4. Compile and upload the sketch to Arduino to read data from the sensor.
5. View PM2.5 and PM10 values on the Arduino serial monitor.

Example code

/* Includi la libreria SDS011 */
#include <SDS011.h>

// Definisci le pin TX e RX del sensore
#define TX_PIN 2
#define RX_PIN 3

void setup() {
  Serial.begin(9600);
  sds011.setPins(TX_PIN, RX_PIN);
}

void loop() {
  float pm25 = sds011.query(PM25);
  float pm10 = sds011.query(PM10);
  Serial.print("PM2.5: ");
  Serial.println(pm25);
  Serial.print("PM10: ");
  Serial.println(pm10);
}

Mini project

Create a real-time air quality monitoring system with Arduino and SDS011. Display data on an online platform like ThingSpeak.

Common mistakes

• Ensure that TX of the sensor is correctly connected to RX of Arduino, and vice versa.
• Check the version of the SDS011 library used to avoid compatibility issues.
• Make sure the sensor is not overloaded or damaged during installation.

Recommended accessories

• WiFi ESP8266 Module
• 16×2 LCD Screen
• 3D Print Case for Arduino
