(should be FF) Co2 PPM = 1 Co2 zzzzZZZZzzzzZZZZzzzz Sometimes the second value is different but the first one is always 1. And obviously 1 is not FF . However I don''t understand what''s wrong in there.

20191028· The difference between analog and digital sensors is that an analog sensor collects readings over a range of values, and a digital sensor only reads a HIGH or LOW signal (a bit of data). The Arduino has a 10bit AnalogtoDigitalConverter (ADC), which maps sensor readings between 0 and the operating voltage (5V or ) into integer values between 0 and 1023.
