Analog CO2 Gas Sensor
Private Ltd Implantaire Technologies (I) 2016-08-05 13:48:36 6933 Views3 Replies Hi,
I'm working on the Gravity CO2 Sensor with Arduino Mega 2560. I ran the sample code from the sensor wiki. i got the readings around 9000ppm - 10000ppm in an indoor room. How do i calibrate this sensor for
1. ZERO_POINT_X
2. ZERO_POINT_VOLTAGE
3. MAX_POINT_VOLTAGE
4. REACTION_VOLTGAE.
Please help me out. I'm stuck.

Here is a picture, maybe you can make a reference:
The datasheet shown in the attachment. Wendy.Hu

Plz read the FAQ on wiki http://www.dfrobot.com/wiki/index.php?t ... EN0159#FAQ for the calibration method. But it requires a commercial CO2 meter which can tell CO2 density first (like this one http://www.ebay.com/itm/Extech-Desktop- ... Sw5VFWQ1z2), or you won't have the chance to calibrate it. Leff
