I wanted to make sure that my results were absolutely maximal, so I used 6 brand new batteries to ensure my voltage going to the RF module was not an issue. Then, I marked the spot on Google Maps on my iPhone, and afterwards I used Google Earth to find the distances. I considered the maximum range to be the farthest point with a clear line of sight that I would pretty consistently get 10 / 10 toggles transmitted. I set the Arduino in my front yard and carried the “client” with me, watching the LED. After I made sure they worked well at close range, I took them out to my front yard, where I’m lucky enough to have a fairly long straight road. one with an antenna) and settings on the NRF24L01+ to see if that would change things.įor the test, I made a sketch that would continuously send a signal to toggle an LED light on and off once per second on a “client” (an atmega328p on a breadboard). Additionally, I tried adding an antenna to the RF module to see if that would help and a couple different models (e.g. Instead, I wanted to try out two even more affordable options that might get me a little extra range: a 433 MHz RF module, and the venerable NRF24L01+. I’ve used the affordable HC05 Bluetooth module for a few small projects, and it worked well, but its range is somewhat limited.

I’m learning some basic home automation stuff with Arduino and Raspberry Pi, and I decided to try out some ways to do things wirelessly. Bottom Line: I tested maximum line-of-site range with an NRF24L01+ and a 433 MHz transceiver that I’ll be using from some Arduino and Raspberry Pi projects.
