I develop a connected electric radiator and I would like to install an IAQ sensor in this radiator to be able to give information on the air quality to the user.
So I bought a BME680 to do some testing. In my living room, I get an approximate constant value of 500 ppm, which is a good level of eCO2. Then, I simulated heating the radiator using a hair dryer, the measured eCO2 exploded around 2000 ppm, which is a bad CO2 level. You can see in the attached picture the stability of the eCO2 measured then the beginning and the end of the heating with the hair dryer.
So I wanted to know if the radiator heat could have an impact on the sensor or if it was just my hair dryer ? If it comes from external heat, do you think it possible to install an IAQ sensor in a radiator ?
Thank you very much for your time,
The temperature around BME680 should not be overheated,otherwise it will affect the output of BSEC, and the actual ambient temperature should be measured.
BME680 HSMI document also mentioned it.
If you would like to install BME680 to radiator, you should ensure that radiator temperature will not be transmitted to the sensor from the structural design.
