ESP32 LoRa Sensor Monitoring with Web Server (Long Range Communication)

In this project, you’ll build a sensor monitoring system using a TTGO LoRa32 SX1276 OLED board that sends temperature, humidity and pressure readings via LoRa radio to an ESP32 LoRa receiver. This receiver displays the latest sensor readings on a web server.

Libraries required (how to install the libraries in the project page):
- LoRa library: arduino-LoRa library by sandeep mistry
- OLED libraries: Adafruit_SSD1306 library and Adafruit_GFX library
- BME280 libraries: Adafruit_BME280 library and Adafruit unified sensor library
- ESPAsyncWebServer library
- Async TCP library
- NTPClient library forked by Taranais

Using the reciever code as boilerplate, great everything you need instructional (the blog not this vid). swapped out the HTML sensor readouts for a table (online table generator), added cell ID's, to color fill with IR array incoming data (TBD). Opens up so many rabbit holes not usually within arduino programmers view. HTML, javascript, AJAX, I never knew the <script> in the HTML page is where javascript lurks. On the ttgo oled LoRa sma board, I2C is default not re-assigned. Great work.

When I upload code to lora using IDE software it shows hard resetting via RTS pin error how to rectify that

Excellent!
Thank you very much for the example.

Hi, this is really a nice project, thank you for publishing it. Please suggest me a pointer, how to add one more sender node. Thank you in advance.

Good morning, i would like to know how can i put 3 devices together and possible and add the mqtt? my idea is to open a remote gate and check if the reed switch is open or closed ... you could do this example. I just joined your channel and I'm already becoming a fan !!

the reference link explains that the measurement results in this project are stable at a distance of 180 meters, what if the required monitoring range is around 10 kilometers? are there additional programs? or change the module type?

Great and useful tutorial gongrats! I have a question for a project of you know how to connect an sw-18010p vibration sensor to the ESP32 LoRa32 SX1276 board ?

[aminaboujnen]

Excellent!
Thank you very much for the example.
but i have a problem in my projet, i don't know how a well communicate the node (is based a lora32u4II ) and the getseway, how i well transfer message to the node in my geteway

hi, bro. my question is a next. for example if i have 3 boards and 2 of this one on 833E6 band one transmitter an the other like a reciver so what will do if i´ll start the thirth like a transmitter on same band but whit other packet??

So, how can do it for to aplly security to my transmition, and dont have interference from other person than choisse the same band?

Hello, i have the problem with this.
When i upload program, on the serial monitor "BME 280 not valid, check wiring"
How about this ?

[ricardoricardo]

Boas Rui, grande video. Parabéns.
Será possivel enviar os dados para um lorawan gateway e aceder em qualquer parte do mundo pelo TTN ?

[jeffegg]

My board Oled seems to have a non standard address. Where can I set this address??

[leggooo]

If the output failed, how do we know where the errors that occur in the system?
Thank you

Rui, how do I change the code to water level instead this sensor? Can you help me?

[danielvieira]

Rui boa noite !
Estou tentando utilizar um módulo cartao sd com o esp 32 ttgo e nao estou conseguindo. Com o esp 32 nodemcu funciona normalmente.
Pelas minhas pesquisas há um conflito entre a comunicaçao spi do módulo lora e o cartao sd

[FernandoSantos]

Boas Rui, grande vídeo. Achas que com um SET de antenas melhor terias um alcançe melhor?

[michaeldudicof]

Can lora module to send image by using Esp32cam ?

[taphoastudio]

I have a project, its the same to your project. My problem is how to build a system webserver for transmit data. another problem is how to change received data to analog data for display on the screen. Can you help me? Thank you so much!

[shrushtihegde]

hello sir any idea how to send message from web server to another device?
