yeah but how much it can affect for example , the range of esp32 c3 dev board with pcb antenna gives 100m of range in an open field ( more than generic rf modules ) . IF we were able to fit high end external antenna to esp32c3 ( custom board ) and used it in a industrial setting , how much range we can get , on an approx like any estimates you can give ?

techielewOP•5/19/24, 12:40 PM

That’s really difficult to answer without knowing more about the environment. The problem is interference (EMI, physical obstructions, etc) in the environment.

techielewOP•5/19/24, 12:44 PM

In addition to interference, how crowded is the spectrum, etc. There is a reason there are all sorts of specialized protocols and technologies for industrial environments.

What sort of data are you looking to send? Check out some of the 802.15.4 options like Wireless HART and Zigbee. @accur4te

the data is sensor reading (rs485) . I was looking forward to send readings of the multiple sensors to a single gateway using espnow and then upload it to the cloud from the gateway @techielew

Lora and in particular lorawan is meant for small data packets every few minutes or so. But you can have thousands of them on a wide range. Anything with needing wide band or critical response time is probably better using other means of communication.

I would embed a tiny computer system in a pair of sneakers that analyzes your running form, tracks distance and pace, and even coaches you in real-time to improve your stride efficiency and prevent injuries! It could connect to a smartphone app for detailed data analysis and personalized training plans.
