DFRobot Gravity: PM2.5 Air Quality Sensor

The DFRobot Gravity: PM2.5 Air Quality Sensor operates based on the laser scattering principle. This involves irradiating suspended particles in the air with a laser to cause scattering. The scattered light is collected at a specific angle, and the intensity of this scattered light is measured over time. A microprocessor then uses the MIE theory algorithm to calculate the equivalent particle size and the number of particles of various sizes per unit volume.

• Expose To Extreme Conditions: Avoid using the sensor beyond the operating temperature range of -10 to +60°C and relative humidity range of 0 to 95%.,
• Obstruct The Sensor: Ensure the sensor's laser and detection areas are not obstructed or covered to avoid inaccurate readings.

• Use In Appropriate Environments: Ideal for environments like smoking rooms, kitchens, hot springs, and bathrooms where air quality monitoring is crucial.,
• Follow Connection Guidelines: Ensure to use the Gravity-4P I2C/UART Sensor Cable provided for proper connection.,
• Check Compatibility: Verify compatibility with main controllers as the sensor works well with most of them.

• Temperature Range: -10 to +60°C,
• Humidity Range: 0 to 95% relative humidity

• Particle Size Range: 0.3 to 10μm,
• Minimum Recognizable Particle Size: 0.3μm

• Description: Use the included Gravity-4P I2C/UART Sensor Cable to connect the PM2.5 Air Quality Sensor to your main controller. Refer to the connection diagram provided in the documentation for detailed setup instructions.
