I am new in LoRa, please suggest 1KM range LoRa module for Arduino.
Please suggest best LoRa module with 1KM range. Also, I want to connect one transmitter and multiple receivers modes. Please suggest
You probably know where you are planning to use the LoRa modules and where the 1km range is required, can you tell the forum so we can help ?
And provide an explanation of what your project actually is.
I am planning to design a wireless bells system for my college, the approximate radius of the campus is 850M. I already tried with NRF24L01+PA LNA but that is not stable and could not work fine. So I dropped NRF. Now I hear about LoRa can transmit 1KM without any difficulties.
If its just a on\off alarm type system then a very low LoRa data rate can be used which increases the range.
If the transmitter is placed at a suitable high point the LoRa ought to be capable of covering the entire area, you may even get away with a transmitter at low level.
All the LoRa modules use the same Semtech LoRa chip so there are no 'good' or 'bad' modules really.
There is more support and libraries available for the SPI based LoRa modules, there are UART (serial interface) based ones but you might have to do your own software.
Most LoRa modules are 3.3V logic, do not use them with 5V Arduinos.
I am designing this system using ATmega328 with Arduino UNO bootloader and RFM95W, can you please suggest a good level converter for RFM95W (3.3V to 5V). Now I setup 3.3v power supply for RFM95W using ams1117 3.3.
I dont use logic level converters, because I dont use 5V Arduinos, so cannot advise.
The cheap logic level converters on eBay are not much good for this sort of application in my opinion.
I use the heck out of these units. I find line of sight range 3km and depending on the obstacle, decent range. They consume little power when not transmitting or receiving. They are UART based, just dont use pin 0 and 1 though. I have several throughout my house transmitting info back to a base so I can see if doors are open or temps in the garage.

And if that range and frequency is not what you need, that company offers several different types
You can easily program through code and I wrote a library specific to these units.
Hope this helps.

Hello everyone,
I trust your kind response would be of great help to me.
I want to use the LoRa module as a communication medium in the project that I will create, but I have difficulty when sending data to be displayed on the LCD 20 * 4, the data sent is still messy, can you help me in this problem that I am experiencing?
