Wireless help needed

[mt92]

I have a project where I need to have a transmitter with 8 programmable buttons that sends a signal to 6 or 7 receivers with a relay for a momentary latch. The receivers can be powered by either 24vdc or 115ac. I need a range of 100-200 yards line of site.
Any suggestions would sure be appreciated.

Thanks

Hi,
You can use LORA Transceivers connect to PLC Modbus.
Best Regards!

Send more information if you would.

I have tried LORA... Its not best suited to simple radio transmission... The distance is brilliant but the packets are designed for large data transfers..

If you follow users of the Arduino platform ( Just because they are readily available and cheap) there will be loads of different modules with code..

Look at the NRF24L01...

Could this all be put into a case with 8 buttons? I guess I am not sure where to start?

Thanks

I suspect those may be illegal to use in both the UK and US, without special licencing.
There are very strict regulation on RF power emission in the 433 MHz band; also "type approval" in needed in the UK.

See the articles below:

Short-range devices

A short-range device is a general term, applied to various radio devices designed to operate usually on a license exempt basis, over short range and at low power levels.

Hi,
Yes you have reason... Thanks for Info., by the way allready found other way, maybe 5Km. is a lot of range for this application.
Best regards.

That helps, I will read up on them to see if the buttons are programmable to control separate receivers.

Thanks!
