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

Product Information

Indoor Air Quality monitoring – The amount of CO2 in a room is a good indication of how well the room is air-conditioned. The CO2 meter uses the most popular components on the market, not the most advanced, and the simplest building without the need of an iron solder. The Arduino IO expasion shield is the best match for this CO2 senor connecting to your Arduino microcontroller . However, over the years we have seen many users use the same-colored jump cables throughout their entire project. The Arduino IO expansion shield is the best match for this CO2 senor connecting to your Arduino microcontroller.

If you do not already have the Arduino IDE software installed onto your computer, please do so now, as we’ll be using it for the last section of this tutorial. LibreCO2: Simple CO2 meter using Arduino UNO and CO2 low cost sensor (Sensirion SCD30, Winsen MH-Z14 or MHZ-19 and Cubic CM1106). This Gravity: Analog Infrared CO2 Sensor is able to directly compatible with the DFRobot Arduino IO expansion board thanks to its external DFRobot Gravity interface. data [Rs ] = calcRs ( readSensor (CO2_sensor ) ) ; //kohm 160 161 data [ CO2 ] = calcCO2 (data [Rs ] ,data [fRHT ] ) ; //ppm 162 163 dataToScreen (labels ,data ,units ) ; 164 165 166 dataToLCD (labels ,data ) ; 167 168 // make a string for assembling the data to 169 log : 170 String dataString = "" ; 171 172 dataString += myTime .Please complete the purchase (or remove the quote – don't worry it's still available in My Account) before adding these additional items.

Now inside the setup() function, initialize the Serial Monitor at a baud rate of 9600 for debugging purposes.There are multiple ways to connect Atlas Scientific sensors to an Arduino, but for ease of use; We will be using a very basic, easy to follow setup that will get our CO2 sensor running in UART mode in no time! You can also utilise CO2 sensors in horticultural applications and they can be very useful to create the correct growing conditions in mushroom cultivation. To change the alarm level from 1000 ppm, by default, to another value between 700 and 1300 ppm you must press button S2-A2 in the shield version, or place an additional cable or switch from pin A3 to A5 in the parts version, for more than 5 seconds and the message "BEEP" will appear, then the value to which it is programmed. Great and powerful sensor for everyone that wants to know the exact concentration of CO2(Carbon Dioxide) in the air.

Using the USB cable type A – B male/male, connect one end into your PC and the other into the Arduino Uno board… you’ll know which end goes where, trust me! I then close the straw and the zip bag (compartment) and I wait 4-5 minutes for the readings to settle. Registered number: 113903 | Registered office: Riverside One, Sir John Rogerson's Quay, Dublin 2, Ireland. dateToString ( ) ; //start with current time and date 127 dataString += "," ; 128 dataString += myTime . It has characteristics such as high sensitivity, high resolution, low power consumption, fast response, anti-water vapour interference, no poisoning, high stability and long life.These two jumper cables will now supply power and a ground line from the Arduino Uno to the EZO-CO2 Sensor.
