PMS5003 (G5) is a digital multi-functional particulate matter concentration sensor, which can be used to obtain the quality and of suspended particles in the air per unit volume and output in the form of digital interface. measurement of laser-scattering principle; real-time response and support for continuous acquisition; stronger anti-jamming performance; optional air inlet and outlet direction.The sensor can be embedded in concentrations of suspended particles in the air or related instruments and equipment to the environment and and concentration data.Measuring Sange: 0.3~1.0; 1.0~2.5; 2.5~10 (um)DC Supply Voltage: Typ:5.0V, Min:4.5V,Max:5.5V; Working Current 100mA; Operating temperature range-10 ~ + 60 .color:BlueMaterial:MetalPackage Contents:1 x air quality detection sensor2 x cableOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
