CO2 Sensor ppm verification
Account cancelled 2017-06-17 07:07:54 1787 Views1 Replies Hello,
I bought "SEN0219 - Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm)" and interface with Arduino uno and Pro mini. on both the hardware the sample code was written, after the code burn and reset, the sensor highlighted CO2 in range of 300ppm-450ppm, and suddenly after several seconds switched to showing range of 1000ppm-1250ppm. the sensor is kept in my own room with wire interfaced and the sensor is exposed to natural air from window. then also it shows such high ppm level. Is there any means to verify the sensor or ppm levels ???
Thanks in advance

2017-07-11 22:38:16 This CO2 sensor has been calibrated before on sale, if you doubt about the value, you can ask them for a replacement, if it's possible, you can have another sensor to compare both outputs to verify the accuracy robert.chen
