Device sends %CO2% instead of the actual value
I played a bit more.. it turned out that while the USB spec says - maximum Voltage is 5.25V, if the USB Power supply outputs more - then the Sensor (also rated at maximum 5.25V does not work any more).
So, when the device fails to communicate with the sensor - it does not populate the %CO2% value - i will fix this by reusing the last stored value

there is yet an unknown reason why the output sometimes fluctates +/- 100 ppm each 10-20 seconds.. i hope to find it soon
