Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm) spiking sensor readings
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
Good Day! I am trying to control the co2 level of a chamber by using the Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm). However, after sometime, the sensor readings spikes at around 34400 ppm. Does anyone ever experienced this? Kindly help me. Thank you.
