PMS5003 (G5) is a digital multi-functional particulate matter concentration sensor designed to measure the concentration of suspended particles in the air per unit volume and provide output via a digital interface. It operates on the principle of laser scattering for accurate measurement, offers real-time response, supports continuous data acquisition, and features enhanced anti-interference performance. The sensor allows optional configuration of air inlet and outlet direction. It can be integrated into various air quality monitoring devices and instruments to deliver timely and accurate particle concentration data for environmental assessment. Measurement range: 0.3–1.0; 1.0–2.5; 2.5–10 (μm) DC supply voltage: Typical 5.0V, minimum 4.5V, maximum 5.5V Working current: ≤ 100mA Operating temperature range: -10°C to +60°C Color: Blue Material: Metal Package Contents: 1 x Air quality detection sensor 2 x Cable Note: Light reflection and differences in display screens may cause slight variations between the color of the item in the image and the actual product. Measurement error allowance is +/- 1-3 cm.
