random() Arduino Reference

Aug 16, 2021· This can be accomplished by calling randomSeed () with a fixed number, before starting the random sequence. The max parameter should be chosen according to the data type of the variable in which the value is stored. In any case, the absolute maximum is bound to the long nature of the value generated (32 bit 2,147,483,647).

Adafruit SCD30 NDIR CO2 Temperature and Humidity Sensor ...

The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration! That means it''s a lot bigger and more expensive, but it is the real thing.
