Thanks for replying @CustomSarge.Alas, the sensors can only communicate using RS485, so using RF would again require me to use converters. Not to mention the interference...
Thanks @matthewbarr.There will be more than one sensor, so there will be a multi drop. The low data rate is fine.About the converters, I just wanted to know which...
I need to connect multiple sensors to the main controller, so if I were to go adding controllers to each sensor, the cost increases.
@Kocsonya, thanks for replying. I need to connect sensors that communicate on RS485 to the microcontroller. The distance can go low upto 250m in most cases.
I require to set up a RS485 connection for a long distance(about 700m) between an ARM cortex M controller and a sensor. I need a UART to RS485 converter but I'm...
