Instructions: 1. This Detector can be used when it on, please use No obvious wind in the surrounding environment, the data stabilized down real-time environment PM2.5 Value,The detector is updated in real time, 1-3 seconds to update the data once. 2. Power supply: Please use mobile phone charger (5V, 1-2A) Please don’t use IPHONE. power bank or computer USB interface power supply. USB interface for Micro USB. 3. This detector is PM2.5 detector, please mainly look at the circle of PM data, air quality index (the first interface lower left corner) for reference only. 4. RST button for the reset use, Please press this button when it crash, refresh the page. 5. Detector is not recommended for continuous use, it is best to select a few time each day, each detection 5-10 minutes enough. 6.USB data cable can always be connected to the detector, each time disconnect the other end of the USB data cable can be, so you can reduce the number of USB interface plug 7. keep the detect dry and clean. Package included: 1 x M5 Particulates PM2.5 PM1.0 PM10 Detector

Overview:   The SDS011 using principle of laser scattering,can get the particle concentration between 0.3 to 10um in the air. It with digital output and built-in fan is stable and reliable.   Characteristics:   1. Accurate and Reliable: laser detection, stable, good consistency; 2. Quick response: response time is less than 10 seconds when the scene changes; 3. Easy integration: UART output (or IO output can be customized), fan built-in; 4. High resolution: resolution of 0.3ug/m3.   Scope of application:   PM2.5 Detector Purifier Air Exchangers Filtering system Working principle:   Using laser scattering principle: Light scattering can be induced when particles go through the detecting area. The scattered light is transformed into electrical signals and these signals will be amplified and processed. The number and diameter of particles can be obtained by analysis because the signal waveform has certain relations with the particles diameter.   Technical Parameters:   No. Item Parameter 1 Measuring output PM2.5,PM10 2 Range 0.0-999.9 ug/m3 3 Power supply voltage 5V 4 Maximum working current 100mA 5 Sleep current 2 mA 6 Operating temperature range -20-50 7 Response time 1s 8 Serial data output frequency 1 time/s 9 Particle diameter resolution Less than 0.3um 10 Relative error 10% 11 Product size 71x70x23mm   Interface specification:   Pin Name explain 1 CTL Control pin, reserved 2 1um >0.3 Micron particle concentration, PWM Output 3 5V 5V power input 4 25um >2.5 Micron particle concentration, PWM Output 5 GND GND 6 R Serial port receiver RX 7 T Serial port transmission TX PS: The pitch of Interface is 2.54mm   Communication protocol:   Serial communication protocol: 9600 8N1.
