Reyax RYLR890/RYLR896 LoRa Tutorial | Sending Sensor Data Wirelessly with LoRa & Arduino

[@devilalg3974]

Thankq so much for making very useful new project. I never find this Lora information anywhere. Thank_you bro.

[@luizcancelacancela7500]

congratulations very cool your projects I speak here from Brazil

[@jumbo999614]

Can signal go through cement wall /ceiling? I want to use this to monitor water level in water tank in my apartment.

[@mramzadg]

another awesome video thank you... sir love u...

[@anwerr37]

I used Arduino micro as a transmitter and Arduino Uno as a receiver for the first example and the LED did not turn on. I can see the transmitter working through the serial port. However, the receiver serial port is not showing anything. do you think Uno is a problem?

[@Lisalisa-kx9fw]

Very cool project and great video 👏

[@081sivasubramanian2]

Does both lora modules comes or to buy them separately?

[@electronic7979]

Very good video

[@naughtykidlavya1680]

Can we do the same thing with Digilent Basys3 Board.

[@martinchlupac4929]

So I wired up to the instructions, loaded the code and the transmitter tx flashes but the receiver rx does not, what do I do now? LED does not come on.

[@woolfy02]

So you can use 2 Arduino Uno boards or 2 nano boards? If you use 2 Nano boards, you just have to drop the voltage from 5v to 3.3v, right?

[@HowtoElectronics]

Better to use 3.3V controller like Arduino Pro Mini or STM32

[@MrAlsan]

Awesome tutorial 👍

[@אילדטינקה]

Great video ! , I have a question - how do I change the code (on the rx AND tx side) so that I can control 2 leds (light - intensity) with 2 potentiometers on the TX side ?

[@arpitlangia8169]

hey, I'm also facing the same scenario. Did you get any solution?

[@joshuakolby1141]

This video really helped me out. It was the first one where I actually managed to send signals. However, there are two things that I would like to know more information about. The first is why is the data sometimes corrupted. For example: Sometimes I will receive "28.63 C" for the temperature one packet, the next I receive something like "28.@3^C". I am wondering if there is a good way to get solid data (I am not in a busy radio area and my devices are 1 m apart with no interference). The next question I have is how to I put input AT commands using SoftwareSerial? I know with the regular Tx and Rx pins, you can just use an empty sketch and the AT commands will work just fine. However, I am unable to use the Tx and Rx pins for my project and have to use SoftwareSerial. I haven't found anywhere online how to access AT commands through SoftwareSerial. Thank you!

[@yogeshitaliya473]

Nice one

[@mr.shaneel5760]

Can you give Proteus simulation for this project

[@joebro391]

Can you explain why on line 32 of the rx_lora script in the first example, you set potval equal to string values in position 9 - 12? I imagine that you're breaking up "cmd" from the tx_lora program as it comes into the receiver, however, if cdm == "AT+SEND=0,, ", wouldn't the actual pot reading start at character 13? For example, in "AT+SEND=0,3,val". Or are special characters (ie, the commas and operators) ignored? Lastly, assuming those characters are ignored and we want the characters from 9 - 12, how does it work if the pot val is only a single digit? Does the program expect 4 characters (ie, 1023) and read "9", for example, as "0009"? Regards, Joe

[@adailyllama4786]

Val in this case is the length of the variables contents.

[@kaibergman1864]

amazing job!

[@kentthomas1045]

What MHZ Band does it work at?

[@ManishGpt]

Again with very nice project but why not Shraddha this time?

[@HowtoElectronics]

She will come in next video bro

[@kpinnovations6613]

Bro great project I was followed all this process as shown in u r video but I have some problems only address is saved in the memory of rylr896 parameters and bandwidth not saved after disconnected from pc and reconnect module with pc all commands are default And I m not getting the range above 100meters pls bro help me

[@billglass5160]

Very good video. I will get 2 Lora modules and try your project. My ultimate goal is to create a remote sensor for my swimming pool water level & temperature using the HC-SR04 and the DS18B20 sensors and an Arduino Nano. By the way, don't you have to send some inital AT commands to configure the Lora modules such as Address, Band, Spreading factor,..etc. ? If so, I will probably need to buy a serial interface FTDI232 board to configure them. Also, for the sensor project, I'm wondering if you know why there are occasional errors displayed on the receive serial monitor com16. And one more point: According to your code, I think Arduinos serial software pins 2,3 are rx,tx respectively. I think the wires to Arduino pins 2,3 need to be swapped. Thanx!!!!

[@billglass5160]

I actually made 2 sensors (1st for water temp. & level, 2nd for outside air temp. & humidity). They are powered by batteries. The first with 3x1.5 AA batteries and a TS5110 timer providing 8 seconds of power every hour. The second with 2x1.5 AA batteries using a standalone ATmega328p running on internal 8 mHz oscillator in sleep mode most of the time. With 3V, no need for the voltage divider on the Rxd Lora device. There are occasional reception misses (1/10) due to interference on the 868mHz channel. I live near a LoraWan gateway and there's a lot of traffic. I confirm my previous comments concerning the FTDI232, errors on using softwareserial library with baudrate>9600, and the rx,tx swapping . I am wondering if using these Lora chips is a little bit overkill. They are a little bit expensive (15 euros) and they seem to have a very long range compared to what is really needed in my case (15 meters). Otherwise, I am satisfied with this project!

[@HowtoElectronics]

Glad to know you are very satisfied. The problem is really with the pricing. The price is too high.

[@billglass5160]

@@HowtoElectronics Good quality though!

[@shrushtihegde9714]

Is there any other lora module which is similar to rylr 890/896

[@HowtoElectronics]

No

[@mnunez6153]

does lora requires always a line of sight condition?

[@ronen124]

No. But like any other electromagnetic wave, the more buildings/trees/mountains between Tx and Rx results in less reception

[@kamshorymt]

Can I replace the antenna?

[@HowtoElectronics]

Yes u can

[@divagarn5468]

bro which gives more range lora 890 or lora sx1278

[@HowtoElectronics]

RYLR890 has the same SX1278/76 chip ibuilt. So basically the range is same for both. But Reyax is expensive.

[@divagarn5468]

@@HowtoElectronics bro what is the max attitude range

[@johnt2895]

Can you better/ more clearly explain the data string format? Do you also do consulting if I needed to hire you for a few hours to help clarify some LoRa packets With sensor data?

[@HowtoElectronics]

We have a team for consulting. You can mail us

[@johnt2895]

@@HowtoElectronics how do I send direct email for more information or consulting?

[@johnt2895]

In your video as an example you have a sensor and potentiometer value. I assume the potentiometer is in volts between 0 and 3.3v. You show a long string of data and highlight the 2 numbers separated by a dot. Is there some user guide that explains this and is it already decided by the recieved as it is transmitted encrypted? trying to understand the Lora packet and how to decide at the gateway with a similar packet string. I am not real familiar with KZbin so how do I PM you or you can send to me a link?

[@AmarSingh-up4vl]

But brother you will not show one transistor value in reciever circuit

[@HowtoElectronics]

That transistor is not the part of the circuit
