The goal is to instrument my air conditioning system. I don’t need to, just want to.
I need to select a microprocessor with 9 analog inputs and a wireless connection. It must have an enclosure to put outside exposed to the weather. The power supply should be in the enclosure. I will provide 115 volts AC. The wireless distance is about 50 feet and through one outside stucco wall and four interior walls. I can program it with most any language. The goal is to send the measured analog signals to my home computer.
Have you any suggestions as to parts and vendor to use?
I'd recommend the ESP32. That has WiFi and >9 analog input pins.
You can program it with C++ using the Arduino IDE (or more low level than that if you don't like Arduino). You also have the option of programming the ESP32 in Python using CircuitPython if you want to go more high level and don't mind the overhead.
As for the specific ESP32 board recommendation, I don't have enough experience to say. I have the NodeMCU 32S and it seems nice enough. The Adafruit Feather ESP32 is fairly popular. I would recommend getting a board with a small form factor since the price of enclosures go up with size.
You can buy nice waterproof plastic enclosures on eBay and Aliexpress in a variety of sizes for a good price:
But you should be able to get that sort of thing from most electronics component distributors and electrical supply stores.
Well, your post got me thinking along the lines I should have thought in the first place. I can search for waterproof enclosures and see what I find. That ESP32 looks good. Now I need to make my parts list, decided how to mount in the box, and determine what I need.
Thank you for taking the time to reply.
You're welcome. Good luck with your project!
