Arduino GSM Project: How to send Security Alert message to multiple numbers using gsm module

[@ambalangodachandrasiri6361]

Excellent, your knowledge of programming is awesome , big respect with my wishes - lucky from sri lanka

[@erboy5546]

Thank`s for sharing those videos. I hope you will continue to do this in the future. Your knowledge of programming is awesome. Big respect.

[@collenfisher3635]

Going to build soon. Thank you for the detail

[@HowtoElectronics]

Great project bro. very well explained.

[@dvnovov7850]

Awesome...! I was searching for same and here it is. Thanks :-)

Hi Sir,can I use Arduino Uno and GSM 900 to send multiple SMS integrated to the dry contact of seismic system?

[@vannamnguyen8515]

Hi sir. After receiving messages. We can reset adruino for next use? How to make auto use. .my English language very bad. Thank you so much

[@Hu4ko]

I tried it just now but I still keep on receiving text messages. I don't know if my idea is right but I'm thinking of adding a function that would limit the GSM shield in sending SMS, like say 3 messages every true values?

[@pookoye]

Is there any AT command for sending SMS to the SIM address book?

[@brahimdahrabou917]

Hi good job I will realize. But if I want to keep the state of 5 or 7 contact how can I do this? Is it possible? Thank you

[@davelodia9157]

This applicable the one your video fire alarm can i use this code for send multiple number

[@aliibrahim8257]

Really awesome super helpful

[@t.v.nagendrababu4261]

Sir, I have used the code given by you in the link. My problem is that the message is going continuously irrespective of the signal (I used limit switch Instead) with delay. Please help me to work only with activation of switch. Thanks in advance.

Wow fantastic tutorial... Can u make video on Lora like this...

[@ElectroniClinic]

videos on lora are available. check playlists

[@dvnovov7850]

Sir i will be showing this project in my project examination, there is only one problem i am facing ,that in lab the signal are so week that the sms from gsm doesn't travel and gsm yellow led is also blinking fast, so it's not in network.But when do it in other place it works fine 😞. Sir is there any signal amplifier device which i can use to increase the gsm n sim card signal. Help plz

[@ElectroniClinic]

yes, you can find an antenna with a long wire. you can search on the Amazon.

Can we do this without LDR only using Arduino and GSM

[@allenjshaju3665]

Can I use 100k ohm resistor if i don't have the one used in video

[@p.k.adhikari9519]

I am using this code and use 3 sensor. It is working, but after sending 10 message..no more message were sent. However the sensor working but SMS no further received in multiple mobile. Please Help!

[@muhammadimrananjum1190]

can we you push button instead of ldr ? if yes then why ?

[@ddddaaddaaaa]

can i send sms from contacts saved in sim card? (without having to include the numbers in the code)

[@Ram-bj1we]

Which type of ardunio use i.e.,range

[@aadityapandya4706]

Greetings! What if I want to just send the messages to multiple people at a time without using the LDR sensor? What changes do I have to make to remove all the components of the LDR sensor from the program?

Sir how we can send the same message to watsapp or face book or any other social media?..I am working on this project please help me..

Bro i m doing lpg leakage detector using arduino n gsm module...can i use 2 mobile num on which i get leakge message.....?

[@abhisheknaik4589]

Bro i m using sim 800 gsm module...wt are the changes to do..in code

[@kvnptl4400]

How can I get the phone number of the sender that is received by the GSM module and use it for sending a reply to that number instead of manually setting the phone number on the code?

[@ElectroniClinic]

The time arduino.reads the message from gsm module store that message in a string variable. And then using my split function u can get access to the number

[@dheerajsreddy5806]

We can send message to 10 numbers

[@paulojoaogumalot8718]

Does this work with SIM800L?

[@enjouratbu3478]

is it possible to dial more than 1 cell numbers?

[@ElectroniClinic]

Yes you can.

Can I use sonar sensor

[@ProPro-li4mz]

Can i sent a group message or broadcast msge using gsm module

[@ElectroniClinic]

yes, you can.

[@ProPro-li4mz]

Bro could u please explain that i have to sent 10 messages at same time in your video it was sent one by one

[@naveenp2347]

it is continuously sending sms, any option to limit sms..

[@camcam3388]

My friend, please, if you have a device code. servo motor control by sms thanks

[@mohsinsiddique2486]

Pls make a video to send non english sms

[@maximolds4764]

I can't send messages. I am doing an earthquake detecting device and it should have a GSM sim900a so I copied the codes and I conclude that it doesn't send messages to the designated numbers

[@ElectroniClinic]

this project is working perfectly. maybe you have modified the code.

[@SrinivasGowd7778]

Hi sir

[@Hu4ko]

Not sent to my second number bro
