Sensor LGAQS-KZ01 - air quality sensor- Seven in one.

Hola buenas tardes, me compré este sensor de calidad del aire,

https://www.alibaba.com/product-detail/OEM-ODM-TVOC-CO2-formaldehyde-detector_60798164887.html?spm=a2700.7724857.normalList.16.255071cdteYwo8&s=p

pero no logro obtener los datos correctamente, le he probado diferentes cosas y nada. ¿podrían ayudarme?

#include “SoftwareSerial.h”
SoftwareSerial mySerial(2, 3); // RX, TX for SDS011 sensor ( to keep Serial monitor available )

// Global Variables
static unsigned char buffSDS[25];// 25
unsigned int PM2_5, PM10 = 0;

void setup() {
// put your setup code here, to run once:
// Read SDS011 on Serial
mySerial.begin(9600); //
mySerial.setTimeout(200);

mySerial.readBytesUntil(0x00,buffSDS,20); // read serial until 0x00 Char received (CR)

// Serial Monitor
Serial.begin(115200);
}

void loop() {
// put your main code here, to run repeatedly:

// Read SDS011
mySerial.readBytesUntil(0x00,buffSDS,20); //(AB)

// Serial monitor, print the HEX bytes received in buffSDS
// Serial.write(buffSDS,10);
for ( int8_t i = 0; i < 10 ; i = i + 1 ) //10
{
Serial.print( buffSDS*, HEX);*

  • Serial.print(" ");*
  • }*
  • Serial.println("");*
    PM2_5 = ((buffSDS[4] * 256) + buffSDS[5]) / 10; // extract PM2.5 value
  • Serial.print("PM2.5: ");*
  • Serial.println(PM2_5);*
    _ PM10 = ((buffSDS[6] * 256) + buffSDS[7]) / 10; // extract PM10 value_
  • Serial.print("PM10: ");*
  • Serial.println(PM10);*
  • delay(500); //*
  • Serial.available();*
