LoRa Arduino Project to control Relay with feedback | Lora Tutorial 2023

In this Arduino project, I have shown how to make the Lora project using Arduino to control relay with real-time feedback using the RYLR896 Lora module. Explained both the transmitter and receiving LoRa circuit and source codes for the Arduino UNO and how to configure the LoRa modules with AT commands.

I have covered the following topic in this Arduino Lora project:
00:33 Quick demo on the Arduino Lora project.
03:43 Explained Transmitter Lora circuit using Arduino Nano.
04:12 Explained Receiving circuit using Lora Arduino UNO
04:43 Explained source codes for Arduino Lora project
09:05 Control high voltage appliance with LoRa Module

Required components for the Transmitter Lora circuit:
1. Lora Module REYAX RYLR896 1no
2. Arduino Nano 1no
3. 220R Resistor (1/4w) 1no
4. 4.7k Resistor (1/4w) 1no
5. 10k Resistor (1/4w) 1no
6. 5-mm LED 1no
7. 0.96" OLED Display
8. Push buttons 2no

Required components for the Receiver Lora circuit:
1. Lora Module REYAX RYLR896 1no
2. Arduino UNO 1no
3. 5v 1-channel Relay Module (Active LOW) 1no
4. 220R Resistor (1/4w) 1no
5. 4.7k Resistor (1/4w) 1no
6. 10k Resistor (1/4w) 1no
7. 5-mm LED 1no
8. Push Buttons 1no

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 band 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 the LoRa project will be within 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. You can also connect a 30A relay to control a pump using Lora Arduino UNO.
8. If you use any other Lora module, then configure the module in setup() as per the datasheet.
9. 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 using Arduino. You can use any other microcontrollers 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 5KM, 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.

Very good an clear explanation. Thanks

[kamaleshbehera]

very good usefull, i am using her pcb from last 1year .

[Nouryas]

Good job! However, there’s just one thing that needs to be corrected. The 4.7 K ohm resistor should not be placed there. Instead, it should be connected between the Arduino and the combination of the LoRa Rx and the 10K ohm resistor. The LoRa should be connected to both the 4.7 K ohm and 10 K ohm resistors. Furthermore, the 10 K ohm resistor should be connected between the LoRa Rx and the GND.

Thanks, I am also interested in this kind of project.

Bro please make video using lora controlling water pump for farmer... Please

[svlicencetochill]

NIce job and thank you. Instead of using momentary switches is there a way to use SPST switches instead?

[swaroopkunduru]

Thankyou. Could you please make similar project for Water tank level monitor and controll switch on and off as per level.

[ShahidPasha-zv]

By using which software did you draw the circuit diagram?

[aakankshabhosale]

Can you please provide program code of this project

[jessevsammons]

Can this be set up to be AAA battery powered ?

[yogendrajamsariya]

I think you should try smart bike controller project ones

[m.shayanshamim]

Can I use Sx1278 lora module instead of this?

[Engineering-chye]

Has anyone actually got this to work? I followed it to the letter and nothing happened. I took it to a professional and there were many errors in the code, mismatched baud rates, and the REYAX of the transmitter is not grounded except through the switches or LED resistor- it has only 0.3v supply!. The voltage dividers are wired wrong the LoRa Rx goes between the resistors not in series. Mine would never have worked and still doesn't, I have not got to the bottom of all the bugs yet. I have wasted many hours on this misinformation. If anyone can get this to work please let me know as I have a use for these and they are exactly what I want so I would like it to work..

[sathiyansuryaa]

LORA based IOTs, required in agriculture field enormously !!!!. Pls work on it.Thanks

[MrArka]

Bro .. please make manually real time and timer relay on and off

[dabhichandresh]

Hi sir .lora module India me kaha se ordar kare .

[ShivamKumar-yfew]

Is this module legal in India and this frequency

[dragon-cucc]

Hello
Blynk Lora vibration sensor alarm for car remote on/off buzzer sound alert

Bhai asa ak circuit banao Jo bijli Jane par mobile par sms a Jaye or bijli Ane par sms a Jaye..

[creativeelectronicchannel]

Why it's take delay after pressing button of transmitter side
