I have a working project running a voltage monitor, which send the data colected to a central point over XBee
The solution includes one Mini Pro Arduino for data collector and Tx and one Arduino Uno for Rx and actuators handling
I Wish like to migrate the whole project to M5. I will use one M5stckC for data collection and one M5stack for actuador handler.
My doubt is around the XBee replacement. The two unit are around 150 feet of distance
Which component you will sugest?
