When you try to combine two sketches of two sensors into one, the work of one of the sensors is interrupted?

Question

Arduino

When trying to combine two sketches of two sensors MQ02 and BMP280 into one, the work of one of the sensors is interrupted + these two sensors transmit information to BLYNK

Answer 1

Perhaps these sensors use some kind of common resources (interfaces, timers, interrupts). It's hard to say for sure without seeing the code.
