There are Arduino shields for CAN, RS-485 and even Ethernet. One from +5volt to SDA, one from +5volt to SCL. That's a different thing. Its for a touring band's stage design and so I am trying to make everything as modular as possible. I came across this article on Hackaday showing a simple AM transmitter sending a morse code tone 700km! I'm looking into a EPIRB for myself while deep in the bush / outback hunting or Ultra-Long Distance Communication with Arduino. There won't be line of sight since it's urban area, but the data Hello everyone. I want to relay information back and forth during the flight from the rocket to the ground at my laptop. My problem lies with the fact that from arduino to the media server will be a Long range communication is quite possible in open areas with very low power - a project I am currently working on incorporates data transmission over 500 KM using only 25 mW (miliwatts) of tx power - this of course relies on a line of sight, and data transmission is at only 50 baud. Convenient RS-485 communication wiring. Open menu Open navigation Go to Reddit Home. If that doesn't work, lower the default 100kHz I2C clock (leave all the resistors in). I no found 50km and 100km RF long range module with arduino tutorial in online. which are commonly used with Arduino, Raspberry Pi in the market uses UART TTL based communicationbecause it only requires 2 wires TX(Transmitter) and RX (Receiver). I mean some devices/units are placed Another option for off-grid communications is to use existing smartphones paired with a LoRa network like we saw in this project. I don't know the limits for the DHT22. I doubt I2C or RS* protocol will work on long distance with such low quality cables. I've been having a weird problem, when I use a laptop or the pc with just the battery of the UPS everything works fine, but as soon as I plug the PC to the power outlet the communication is lost. Project Guidance. Post your findings. Interfacing. Should I use a wifi module, but then how would I create a non-local server?
