Spikes in CO2 and TVOC measurements with CJMCU811 sensor

1. I saw similar behavior from 3 CJMCU811 sensors that I bought (in one order, so probably the same manufacturing lot) in mid 2019. Two gave readings with steady, spikey, but uncorrelated upward growth. The third periodically spiked into the 20003000 ppm zone and then popped back to ~450 ppm (in an empty room with decent airflow).
