PMS7003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of a digital interface. This sensor can be inserted into variable instruments related to the concentration of suspended particles in the air or other environmental improvement equipment to provide correct concentration data in time.
The sensor uses the principle of laser scattering. It means that the laser light on the particles in the air and making the scattering, while collecting scattered light at a particular angle, resulting in scattered light intensity with time curve. The principle of laser scattering is to achieve accurate measurement. Minimal resolution particle size 0.3um.Zero error alarm rate.Real-time response and support for the continuous acquisition. Inlet direction is optional, the use of a wide range of users without the need for duct design. Ultra-thin design, only 12mm, for portable devices.USB to TTL serial download cable, compatible with win XP / VISTA / 7/8 / 8.1 system, can emulate existing applications on the COM port based on most operating systems and can easily adapt to any connector and handheld device. Power supply voltage: 5V.
