Hello. I would like to control a relay between certain values using a CO2 sensor, humidity sensor, and temperature sensor with an Arduino Nano. I would appreciate your help with the PCB, schematic, and code.
Thanks.
Sorry, but the forum is not a free code writing service. To request a help you need to demonstrate your own attempts to resolve the problem.
Did you try to write the code? To make a connection diagram? Please show your efforts
