I am not new to arduino but I can't seem to find any help on what I need. I want to create a weather station outside with a dht 22 (3pin), an arduino nano, and an esp8266-01. Inside the house, I would like another module that would have a dht 22 (3 pin), an arduino uno or nano, a 16*2 lcd display and another esp8266-01. The module inside the house would then recieve data from it's own dht22 and from the module outside (over wifi) and display it all on the lcd (and on a web server if possible). I don't know where to start. Please help.
Split the project into smaller parts and make one part at the time.
Hello the_coder
Either:
Post your sketch, well formated, with comments and in so called code tags "</>" and schematic to see how we can help.
Or:
Run some tutorials for the hardware selected.
If you are happy with the results of the tutorials you can merge these to your project.
Have a nice day and enjoy coding in C++.
Hello I am no expert but you CAN enlist some online resources such as “15 minute Engineer” (Or is it “5 minute Engineer”). This website will give you wiring and coding examples to help you get up and running…..
Good luck!
I'm not sure what the Nano is for in the outside module. The esp-01 should be able to read the sensor by itself.
The same is true for the inside module, if you switch to using an LCD with an i²c backpack and a sensor which also uses i²c, like sht2x/3x or similar. Perhaps even a bme280, which can also measure barometric pressure.
