SDS011 Nova PM Sensor Laser PM2.5 Air Quality Detection Sensor Module

Description

The SDS011 Nova PM Sensor is an air quality detection sensor module designed to measure particulate matter (PM) concentrations in the air. It primarily detects PM2.5 (particles with a diameter of 2.5 micrometers or smaller), which are small enough to be inhaled into the lungs and can pose health risks.

Here are some key features and information about the SDS011 Nova PM Sensor:

Key Features:

1. Measurement Range:

   • PM2.5: 0-500 µg/m³ (micrograms per cubic meter)

   • PM10: 0-1000 µg/m³

2. Laser-based Detection:

   • The sensor uses laser light scattering technology to detect particulate matter in the air. This method is highly accurate and effective for measuring the concentration of PM2.5 and PM10.

3. Working Principle:

   • The sensor uses a laser diode to emit light, and when the laser hits particles in the air, the particles scatter the light. The sensor detects this scattered light, and the intensity of the scattered light correlates with the particle concentration.

4. Interface:

   • The SDS011 sensor provides a UART (Serial) interface for communication with a microcontroller or other electronic devices. This allows the sensor to easily integrate into projects such as air quality monitoring systems, IoT applications, and environmental monitoring.

5. Accuracy:

   • The SDS011 is designed to be relatively accurate in detecting PM2.5 and PM10 levels, making it suitable for both home and industrial air quality monitoring.

6. Low Power Consumption:

   • The module is optimized for low power consumption, making it suitable for battery-powered or remote sensing applications.

7. Calibration:

   • The sensor comes factory-calibrated, but it can also be re-calibrated if needed using known reference data.

8. Compact and Lightweight:

   • The sensor module is relatively small, making it easy to integrate into various projects.

Applications:

• Air Quality Monitoring Systems: Used in home air quality monitoring systems to track PM2.5 levels and ensure a healthy living environment.

• Smart Cities: Integrated into urban air quality monitoring systems to measure pollution levels and provide real-time data.

• IoT Applications: Used in Internet of Things (IoT) projects for environmental sensing.

• Environmental Research: Helps researchers gather data on air quality and particulate matter in various environments.

Integration:

To use the SDS011 sensor with a microcontroller like an Arduino, Raspberry Pi, or ESP32, you can connect the sensor’s UART pins (TX and RX) to the microcontroller and communicate through serial communication. Libraries and example code are available for popular platforms like Arduino IDE to facilitate the integration process.

Important Notes:

• The sensor is sensitive to temperature and humidity, so it’s important to consider environmental factors in real-world applications.

• The sensor has a built-in fan to ensure airflow through the sensor for accurate measurements.
