Blynk 2.0, Arduino, DHT11 and SIM800L | Send Temperature and Humidity Data to Blynk using GSM Module

Today, we will learn about how to send temperature and humidity data to new Blynk 2.0 using Arduino UNO, DHT11 and SIM800L GSM Module. In this project, I have used SIM800L GSM Module. I used this because, this project needs internet connectivity to send data to Blynk cloud. and I used the GPRS feature of SIM800L to connect to the Blynk server, and send temperature and humidity data to Blynk cloud.

Parts:

0:00 - Demo
0:32 - SIM800L
1:23 - Required Components
1:36 - Wiring Diagram
2:10 - Setup Blynk Account
2:44 - Create Blynk Data Stream
3:25 - Create Blynk Web Dashboard
3:56 - Add Device to Blynk Template
4:23 - Project Coding
6:01 - Setting up Blynk App
6:41 - Blynk Connectivity on Serial Monitor

Can u give demonstrate for Arduino with usb for connecting blynk 2.0

[raymondmichael]

Thanks buddy, can you create another tutorial just like this but using firebase v9 or mongodb!?
I had trouble posting to a long url using this gam module.
Hopes you can shade some light

Hi, i have successfully done as per your tutorial and it was fun. Thanks man.
Can you do the code for ACS712 current converter module which also connect to blynk server.. thanks in advance

For gsm, is use 2g network only ah?, other networks support r not?

[simukupaulinuskambinda]

I tried the same code, the gsm goes online for 10 seconds and stop which means the gauge updates only during that 10 second of connection and then stops. Is there anything I'm missing?

[joseneyargonsula]

hi bro.. can we use the same code if we use SIM900 module? thanks

Hello, I Have Sim 800L but problem is that it's not responding to AT command. my power supply is correct because sim is working inside sim800l but when AT command is not working. any solution is available?

[TechTrendsShameer]

Bro. I tried the same projects, but I am getting the message as "Cannot Init" in Serial Monitor. Can you please help to solve this?
I am using GSM 800.C module

[ihebjallouz]

hey does it work if i change arduino with esp32

[endekan]

Excuse me sir, in my project at serial monitor writed invalid auth token. Can u help me sir?

[TechTrendsShameer]

I solved the error Cannot Init. But Now I am facing another error. The serial monitor always says "Failed to read from DHT Sensor" I tried all the pins in the GSM. But still it is same. Please help me bro.
