ตัวอย่างการต่อวงจรและ Code

Required Libraries :
1. EspSoftwareSerial (https://github.com/plerup/espsoftwareserial)
2. PMS library (https://github.com/fu-hsi/pms)


#include PMS.h #include SoftwareSerial.h EspSoftwareSerial::UART testSerial; #define RX (21) #define TX (22) PMS pms(testSerial); PMS::DATA data; void setup() { Serial.begin(9600); testSerial.begin(9600 EspSoftwareSerial::SWSERIAL_8N1 RX TX false 95 11); } void loop() { if (pms.read(data)) { Serial.print(PM 1.0 (ug/m3): ); Serial.println(data.PM_AE_UG_1_0); Serial.print(PM 2.5 (ug/m3): ); Serial.println(data.PM_AE_UG_2_5); Serial.print(PM 10.0 (ug/m3): ); Serial.println(data.PM_AE_UG_10_0); Serial.println(); } // Do other stuff... }

PMS3003 using laser scattering theory be able to get in the air suspended particulate matter concentration of 0.3 to 10 microns and reliable data; built-in fan digital output high integration.

คุณสมบัติ
- Data is accurate: Laser detection stability consistency.
- Fast Response: scene-change response time less than 10 seconds.
- Ease of integration: serial output (or IO port output can be customized) comes with a fan.
- High resolution: minimum resolution particle diameter of 0.3 microns.

Works

Using laser scattering theory: When laser irradiation by detecting the position of the particles will produce faint light

Scattering in a particular direction of the light scattering particle diameter related waveform waveform classification by different size system

Account the conversion formula can be different sizes in real-time particle number concentration in accordance with the calibration methods
