Infrared CO2 Sensor SKU SEN0220

Introduction

DFRobot released its latest wide range infrared CO2 sensor, which effective range is up to 0~50000ppm. This sensor is based on non-dispersive infrared NDIR technology and has good selectivity and oxygen-free dependency. It integrates temperature compensation and support UART communication mode. Most importantly, the product is easy to use it is compatible with all types of microcontrollers with UART port, like Arduino, Raspberry Pi and other microcontrollers. Besides, it has a long service life, up to 5 years! In addition, this UART Infrared CO2 Sensor is a high-performance sensor that combines technology of mature infrared absorption gas detection with precision optical circuit design as well as sophisticated circuit design. It has characteristics such as wide range detection, high sensitivity, high resolution, low power consumption, fast response, anti-water vapor interference, no poisoning, high stability and long life. It can be widely used in HVAC refrigeration and indoor air quality monitoring, industrial process and safety monitoring, agricultural and animal husbandry production process monitoring, etc..

Serial.begin 9600 while !Serial
mySerial.begin 9600 ;
void loop mySerial.write hexdata,9 delay 500 ;
for int i=0,j=0;i<9;i++
if mySerial.available >0 long hi,lo,CO2 int ch=mySerial.read ;
hi=ch //High concentration
lo=ch //Low concentration
if i==8

CO2=hi*256+lo //CO2 concentration

Serial.print "CO2 concentration " ;

Serial.print CO2 ;

Serial.println "ppm" ;

Expected Results

Open your IDE serial monitor and wait for about 3 minutes preheat process , then you'll see the finial data. Indoor Temperature 25
