GDS06 Infrared PM2.5 Sensor Model Product Details
1 product summary
Infrared Particle Sensor module
GDS06 By using the principle of optical radiation, the dust sensor products by thetransformation of the light path and circuit, measure the dust density in the range of themeasurement, can be directly application of single-chip microcomputer UARcommunication. Small size, high precision, low power consumption, wide measuringrange, short response time and quick application.

1.1 applications scope
◆ Air purifier
◆ Portable detector
◆ Other household electrical appliances
◆ Automotive air purificationFresh air systemIntelligent detector
◆ Fresh air system
◆ Intelligent detector
1.2 the basic features
◆ In principle this product only applies to the above applications. When used for otherpurposes, users are required to authenticate themselves.
◆ Please far away from the high frequency high voltage placing signage at the product, inorder to avoid the interference caused by high frequency high voltage.
◆ No rule of the violent vibration will cause the product measurement error increases.
◆ Outside light will cause the measuring error of the products increases, so when installedon the equipment, should try to avoid the outside world of incoming light.
◆ This product inspection hole not plug or objects into larger particles, please install behindthe screen. Recommended filter size: 10-20 m um, thickness: 3-5mm.

1.6 data transmission
Sensor with a standard full duplex UART serial port communication with baud rate to 2400BPS, can choose the chip selection terminal baud rate is 9600 BPS, when apply it, the only need toreceive the dust density data, sensor default to continuous work. Ash resulting from the serial portdata decoding the unit of dust density is μg/m³, you can modify the query response mode ofthe serial port through the command.
Detailed serial communication format and data decoding refer to appendix 1.
The sensor outputs PWM signals via PWM mouth (fourth foot), the PWM period is 2S, and thedust thickness is calculated by low level width. The pulse width of the pin output corresponds to theaverage of the dust density.
Relationship between low pulse and dust density: 1ms = 1μg/m³ .
For example, low level width is 100ms, and the dust density is 100μg/m³.
The density output range is from 1ug/m3 to 500μg/m³. Software filtering is performed internally, and the beat is relatively small.

4 way of installation
◆ Installation should be in the vent of the air .
Air velocity: 1.5 ~ 3 m/S wind: 0.004 ~ 0.01 CMM
◆ When install it, please puts LUFTMY logo above;
◆ When the sensor is mounted, please hold at least the sensor. There is no morethan 5mm of space in front of the ventilation hole;
◆ It is suggested that the air filter cotton with 3 to 5 millimeters thickness shouldbe added to the ventilation hole near the inlet of the machine to prevent theaccumulation of large particles such as dust and wool chips;
