LoRa Project Arduino ESP8266 control Relay with feedback | Lora Tutorial using RYLR998 Lora module

In this Lora tutorial, I have shown how to make the Lora project Arduino ESP8266 control relay with real-time feedback using the RYLR998 LoRa module. Explained both the transmitter and receiving LoRa circuit and source code and how to configure the LoRa module with AT commands.

Important points:
1. The Network ID and BAND should be the same for the transmitter and receiving end Lora module.
2. Set the BAND as per the eligible LoRa bands in your country.
3. You can use any other microcontroller for this Lora project.
4. All the AT commands for configuring the LoRa module are written in the void setup() function of the source code.
5. The range for this LoRa project will be up to 5KM in rural areas. (Range will decrease if the number of obstacles increases in the signal path).
6. After the restart you have to wait till the STATUS LED turns OFF.
7. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.

During this Lora tutorial video, I have explained all the required information to make this LoRa project. You can use any microcontroller with the LoRa module. Both the microcontroller and LoRa module communicate through the serial terminal at the 3.3V logic level.
The range for this LoRa module is up to 10KM, So this project is very useful in rural are where WiFi is not available. The range may decrease in urban areas due to more obstacles in the path.

I have RYLR998, when set band using At command it remember only when it is connected, when i disconnect and connect and ise "AT+BAND?"
it shows why it is not remembering BAND?

[RayES]

Great project, making this one. Like to try it without the pcb.

[paiboonpanuwattanawong]

Very interesting and I am thinking of using this for my farm.

[woolfy]

The tutorial only has the Gerber file to download. What happened to the BOM / PIckAndPlace ones? I wanted to get the PCB board made but, I'm stuck without it.

[RianHidayat-czyi]

hi, why we have to use relay? can we bypass without using relay? so it executes intantly without delay?

[shockk]

i cannot see buyying option in the ryax module it is very difficult to buy iy so please tel me alternative modules

[frank]

Hola, podría hacer con el módulo Lora ra-01 sx1278?

[senthiltpsp]

Which antenna to use increase the range

[ajeet]

may i know which site u use to draw the circuit diagram? i had searched many but some of them are missing with components.

[szarkakohegy]

Do you also have a code for Heltec ESP32 LoRa V3 with display?

[JorgeMedina-by]

It's possible using The Things Network?

[mypc]

Bro above links for lora purchase is not working.can I get indian purchase link please.

[EL]

Can use another nodeMcu/esp8266 instead of the arduino receiver ?

[bilalhajji]

Can we use lora-02 white the same shematic and code !?

[yojithkr]

What's the practical range of communication?

[chipmaster]

Puedes hacerlo asi pero que controle 2 placas de 4 relay cada una ?

[matthiash.]

Super project 😀👍
Quick question: Where do I find the Lora tape for Germany and the other settings (Lora Networkid etc.) where I need for the code ?

[gottisttot]

Hi man, can help with a video, where you control L293D motor DC with Alexa and ESP8266?

[ElectricalMCU]

Can this Lora model transmit temp & soil resistance for the same distance in addition?

[shockk]

bro, alternative lora module could you please suggest me for this project
