In this project we’re going to create an SMS notification system with the T-Call ESP32 SIM800L module that sends an SMS when sensor readings are above or below a certain threshold.
In this example, we’ll use a DS18B20 temperature sensor, and we’ll send an SMS when the temperature is above 28ºC. Once the temperature has decreased below the threshold, we’ll send another SMS alert.

Great video as always! Keep the good work! Could you do a video using Google or Azure IoT cloud with this board?
Thanks for the nice tutorial !!
After reading it I purchased a couple of TTGO T-Call ESP32 SIM800L.
The only problem I have is that the code is not compiling as the SoftwareSerial is missing.
As I read on the internet, SoftwareSerial was removed from the Arduino libraries and became “board dependant”.
That means that if I compile for “Arduino MEGA” SoftwareSerial is there. If I compile for ESP32 Dev module, SoftwareSerialis missing.
Any help?
Amazing video. Good job! Would you know to show how to read SMS sent to TTGO T Call?
Very nice video, please speak about communication between two devices esp32 with esp now protocol. Thank you.
May I ask what the benefit is of the ESP Tcall is over the Nano TCall?
Is it the addition of WiFi and Bluetooth?
Does the ESP also have a RTC (unlike the Nano) and thus can be put into Deep Sleep mode?
Thank you
Good video.
Which module is available for 4g (small size), 3g sim cards(big size)?
Thanks
Please make tutorial that receive an sms. Thanks!
Great work sir! But i have question do you know how to make call alert?
The tutorial is very useful, our plan is to make river water level detection.
I think LoRa would work better for your project since that method consumes less energy and you dont have to pay for sms
Can this be done without a sim, in other words with a simple esp 32 or 8266
So you need to have a 2G sim card? My sim card doesnt work... :( and whats the fréquence od the external antenna??
Hi Sir. Can u please make a tutorial video project for ttgo t call to control 4 channel relay with micropython program skript???
Can you show how to use pir sensor with this board for sms alert
What is the name of the antenna you used in the video ?
well done
Thanks for watching
Please make video on TTGO-T-TCALL ESP32 SIM8000 Connect to Firebase
excelent
make an RFid Attendance tutorial connected to the data base
The libraries you use do not appear in the library manager, how did you do it?
sir if I want to operate with both normal SMS and gsm data then what should I do ?
sir my TTGO T CALL is not properly working with blynk server
It goes offline after some time and do not reconnect till the main power goes off
So i request to you kindly make a video on A RELAY CIRCUIT BY SEND AND RECEIVE SMS as feedback using TTGO T CALL
How to connect battery in this breard board
Greetings, thanks for the tutorial.
Can I connect two 18650 lithium batteries in parallel to the module (TTGO T-Call ESP32 SIM800L)? Can the power manager supply enough current to charge the two batteries in parallel?
I have the same question... I'm looking for this answer in many foruns but still can't get the information
@@AryVinicius I asked the question of the author of this video th-cam.com/video/QgDPsXgNsc4/w-d-xo.html he answered the following, however, I have not yet tested: Yes.. You Connect parallel tow batteries that was perfect working.

Dear sir we want 12v DC battery charging status with TTGO T CALL ..(if bettery voltage is reduced from 11 volt SMS coming required) if possible Please help and make a vedio about in this project.
I think that this would actually work even if your current network doesn't support 2g since SMS still works the same way in later networks like 4g and LTE. What do you think?
ever heard that classic old phone that have no 3g or 4g in it ? only 2G. Basically sim800l is like that only support 2G, the problem is in the device which is not support 4G and LTE, not about the network
Sir,thanks for this tutorial.I have a question.I use ESP32 with external SIM800L.I use UART0(TX0 and RX0).What do I have to change in this code?Please help me.I tried so many things.
ilker aykut did that work for you? I want to do the same.
Did you take any other steps when flashing? I'm trying with platformIO and getting "Failed to connect to ESP32: Timed out waiting for packet header". On some other ESP32 boards it's fixed by pressing boot button but this one does not have it.
Does your USB-C cable has data pins? If it's just a power USB-C cable from a powerbank, they often are charge only. Do you see your ESP32 board appearing in the Port menu?
@@RuiSantosdotme Yes, actually i kept trying and it works like 2 in 10 attempts if i keep hitting the EN button. Does yours just update without touching any button?
Make a GPS tracker
Ooo good jobs i love your video ,This module support 4G ?
Unfortunately no... In a few weeks, I'll get a standalone module that supports 3G and 4G, but it's way more expensive (probably around $80)
0:40 "This module will only work if your country is still support 2G". If you love his video, so why you didn't watch it? Or you're that stupid you can't even understand this simple sentence?
Don't worry , I think he was just asking if it supported 4G
@@RuiSantosdotme I think the answer on this question is more than obvious from the statement "This module will only work if your country is still support 2G"
@@RuiSantosdotme thank you very much for your answer and your time
Olá Rui, qual achas que é o melhor tarifário para IOT ?
Depende muito da utilização, mas talvez um pré-pago com X número de SMS por mês. O melhor mesmo é imaginar o uso que vai ser preciso e tentar ver as alternativas com todas as operadoras
Make a GPS system
Good Morning bhaya......
I have a project,
Am work a one small company.
I need GSM Module board with 12Relays.
We have to Control this with mobile.
1st Relay-----Generator start Relay 10sec need to close.
2nd Relay------Generator Off
Relay 10sec need to close
3rd Relay-----Generator suplay on need close our timings.
And remaining Relays
4th Relay----- If 230v Mains Fail we have to get Message/Mains Fail Alaram, if Mains Power Available / Mains Power Restored.
5th Relay------If 230v Generator ON we have to get DG ON Message, If DG Stop / DG Stop message.
6th Relay------If 230v Load suplay Available we have to get Power Issue clear message, If Load suplay not available we have to get Power Issue.
Is this possible
Please send me ardunio board
Sir rui, I tried your simple "Hello from ESP32" send sms, but it just says "SMS Send failed" please help me ,I badly need this to work thank you
I am using a esp32 and a separate sim800l gsm module
@@gab1861 Could you find solution?
@@ilkeraykut7064 yes, just connect it to your esp 32 and find a simple send sms code, I would suggest you use AT commands
@@ilkeraykut7064 I can send you my codes if you are having hard time
@@gab1861 yes I appreciate it.
Muito bom
Thanks! (Obrigado)
This module requires a lot of current when it's not IDLE, better use a +2A phone charger or lithium battery when testing.
Micropython version Anyone????
