The ALLNET MSR Sensor ALL4472 / Fine Dust Sensor is a high-precision particle (PM) sensor, ideal for monitoring air quality indoors and outdoors. This revolutionary sensor measures particles with a diameter of up to 2.5 micrometers (PM2.5) and 10 micrometers (PM10), which are critical for assessment due to their potential health impacts.

Key Features

• Compact Design: Measures just 40.6 x 40.6 x 12.2 mm.
• Wide Operating Temperature Range: Operates effectively between -10 and +60 °C.
• High Measurement Accuracy: ±10 µg/m³ at low concentrations and ±10% at high concentrations.
• Detection of Small Particles: Capable of detecting particles as small as 0.3 µm.

Performance Upgrades

The sensor utilizes laser diffraction technology, ensuring high accuracy and reliability. It is designed to maintain this performance for over eight years.

Technical Specifications

• Power Supply Voltage: Operates at 4.5 to 5.5 V.
• Average Power Consumption: Less than 60 mA at a measuring rate of 1 Hz.
• Compatible Interfaces: UART, I2C, and RJ45.
