DFRobot Gravity: Analog CO2 Gas Sensor for Arduino | CO2 Gas Detector

Product Information

If the message is "fail" then the connection failed and we must verify the connection between the Arduino and the sensor. Since i never worked with similar sensors, i dont know if is even possible to do measurements in the outdoor (not placing the sensor inside the sewage drain), in a relative fast way (ie: not leaving the sensor for hours in the location). I´m also looking for a cheap co2 sensor, but for outdoor measurements, it should have high range (=>10000ppm) , but the accuracy is not a requirement, i´m looking for in the thousands range.

After fulfilling these conditions, you must press the S1-A1 button in the shield version, or the "switch" in the version by parts, for more than 5 seconds, and the "cal-" message will appear on the screen, counting down 5 minutes for the Sensirion and Cubic and 20 minutes for the Winsen.My calibration process goes, I have placed both sensors (1 cozir and 1 Vernier sensor) in a closed compartment (zip bag) and breathed through it using a straw. println ( "Card failed, or not present" ) ; 72 // don't do anything more: 73 while ( 1 ) ; 74 } 75 Serial .

If any of you have used these kind of sensors before and have had a positive experience with the sensors you purchased, please let me know the details.

I have included a list of the most frequently asked questions about projects built using Arduino and the CO2 sensor. By knowing the exact concentration of CO2(Carbon Dioxide), we can do something to reduce the CO2 and to protect our Earth. Then, create an Adafruit display instance with the width and height defined earlier with the SPI communication protocol.Perfect for environmental sensing, scientific experiments, air quality and ventilation studies and more. With a perfectly blended team of Engineers and Journalists, we demystify electronics and its related technologies by providing high value content to our readers. Make sure all your jumper cables are fully connected on both the EZO-CO2 Sensor and on the Arduino Uno board before moving on to the next step.

a) Unplug the device from your computer and screw the top and bottom portions of the enclosure together to complete the assembly.By knowing the exact concentration of CO2, we can do somehing to reduce the CO2 and to protect our Earth. dateToString ( ) ) ; 107 108 //fill data array with fresh measurement results 109 double data [numData ] ; 110 data [Td ] = calcTemp ( readSensor (Td_sensor ) ) ; //degrees C 111 data [Tw ] = calcTemp ( readSensor (Tw_sensor ) ) ; 112 data [pWd ] = calcPw (data [Td ] ) ; //kPa 113 data [pWw ] = calcPw (data [Tw ] ) ; 114 data [ RH ] = calcRH (data [Td ] ,data [Tw ] ,data [pWd ] ,data [pWw ] ) ; //dimensionless 115 data [fRHT ] = calcfRHT (data [ RH ] ,data [Td ] ) ; //humidity and temperature correction factor, dimensionless 116 data [Rs ] = calcRs ( readSensor (CO2_sensor ) ) ; //kohm 117 data [ CO2 ] = calcCO2 (data [Rs ] ,data [fRHT ] ) ; //ppm 118 119 dataToScreen (labels ,data ,units ) ; 120 121 dataToLCD (labels ,data ) ; 122 123 // make a string for assembling the data to log: 124 String dataString = "" ; 125 126 dataString += myTime .
