I am working on an industrial iot project using esp8266 programmed using Arduino IDE.
problems:
when i say industrial i am not just talking about temperature.
so I am now planning to migrating to ESP32. Will that solve my problem?.
Specifically I am planning to use ESP32 S#
Generally dev boards are not the best choice for industrial environment.
For best reliability, you should search for something specifically designed.
However, in my personal experience, ESP32 based cards are less prone to crash due to de the more resource available.
WiFi comms is short range and probably not suitable for large areae with a lot of interference.
What is industrial for you? Lots of motors, high current circuits, etc?
Anything radio based will struggle in such environment, and lots of care will need to be put into signal processing and proper protection against EMF etc. Small dev boards are often not fit for the job.
That’s also why a lot of manufacturing sites use wired technology and industrial bus based communication protocol have been developed
ok, so how about ESP32 S3.I mean compared to ESP32 dev module. Any talk about it being superb, better or worse than esp8266 or esp32 dev module
@J-M-L I think you got the intention of my question. Well yes by industrial I mean Out doors, lots of metal, gas tanks etc.. And yes, like u said lots of care should be put into protection against these boards. So how can I achieve that? Any stress test or research or anything of that sort regarding protection of ESP8266/ESP32 or any dev modules in general.
I am curious because there are some ESP8266/ESP32 based industrial iot gateway products in the market like norvi. how can i achieve something similar? - a stable product.
Will migrating to esp32 with ample protection measure help?
Well you have already said that the WiFi fails in your environment. I would not expect that swapping between different versions of ESP8266\ESP32 will help much, they will have pretty much the same type of WiFi transmitters and receivers.
Modules that allow for the fitting of external antennas will probably help, the PCB antennas on ESP modules are fairly poor.
Or switch to a different type of module.
The 2.4Ghz LoRa devices can run at high speed over short distances but also have the benefit that if you slow them right down you can get line of sight ranges in the 80km+ region.
IECEx/ATEX constrains may apply to what you do…
Sounds like a serious industrial project.
Are there significant consequences if it fails or is just not reliable ?
