Product Name: Fresh Air System LED Display Dust Monitoring System Pm 25 Optical Dust Sensor Model NO.: D661 Customized: Customized Output Signal Type: Relay Output Type: Optical Sensor Trademark: LOGOELE Transport Package: Anti-Static Bag Packaging Specification: 15X15X10 cm Origin: China HS Code: 8538900000 Product Description Product overviewFresh air to the system controller is at the request of customer custom development. Mainly used for the detection of environmental dust particles in the real-time data, when the number of particles than setting the alarm density master control board, main control board control relay action, make the exhaust equipment work. To achieve intelligent control effect. The sensors density can freely set, the default setting is 100 mu g/m3, environmental concentrations of more than 100 mu start fan work after the g/m3, fresh air to purify air so as to realize the environment;The concentration alarm value can be set freely, the concentration alarm value setting range is: 1-999 micg /m3;The system integrates the sharp, the latest generation of dust detection sensor, small size easy installation, the sensor can detect more than 0.03 microns particles in the air, such as cigarette smoke, house dust, mold, pollen, spores, etc., when they are in a sensor detection range, because the dust produced by light scattering, scattered light into the light receiving element, converted to electrical signals, then after a series of algorithms in the form of voltage output, sensor light resistance, good, can be used for a variety of environmental testing.Application scope:It is suitable for factories, workshops, offices, supermarkets and other crowded environments. Sensors can intelligently identify dust concentration and output dust in excess of concentration.
