  • Arduino Tutorial: GSM/GPRS SHIELD (SIM900) SMS Send and Receive Tutorial on Arduino Uno
    In this video we are going to see, how easy it is to send and receive SMS messages using the Arduino GSM/GPRS shield (with SIM900 chip) from Tinysine. The shield is capable of sending and receiving SMS messages as well as making and receiving phone calls. It can also connect to the Internet using the GPRS network. But we will take a look at this later on in another video.
    In this video, we connect to the GSM network of COSMOTE in Greece and we send an SMS message to a cell phone. Then we reply to Arduino and read the message in the Serial Monitor in the computer.

    Thanks for the Tut. I just got one from Banggood. Yours has extended pins on the bottom, the ones supplied from Banggood are just normal pins. I would suggest buying from a reputable supplier.

    thank you. Do you have an example with same shield and library to use for AT commands from serial monitor? In this video 2:53 what does it mean to not forget to disable PIN at SIM card?

    That was killer! :-) Although I don't have a GSM service or any cellphone service mind you, to build one of these and test it , some ideas are still going through my head. Like taking a keypad and create your own dialing pad. I don't think that would be too hard to do. There's also a wiring diagram out there to make a keypad to run off of just two wires, using resistors. That would be cool!! I'm sure it shouldn't be too hard. :-)

    where do you get sim cards from? Do you have to pay for some service on the sim card that goes into the gsm module?

    Hi, thank you for your video...it WORKS...but i have a question: why in my Serial Monitor interface shows me some code like that..
    ATT: +CPMS:
    RIC:
    +CPMS.
    OK
    ATT: OK
    RIC:
    SHUT OK
    etc
    And then the confirmation of the status and sms sent
    Do you have any idea why shows me all this ATT info etc..
    Thanks

    this great Mister...
    but in other case, now i am still doing my project about monitoring home energy comsumption and used module gms sim900 for long distance communication . in this case, first i want send sms including code, example " data from room A " to modul sim 900 and then modul will automatic reply the data from room A , example in this case the response messenge body is :
    i= 2 ampere
    v= 220volt
    p= 23 w
    kwh = rp1256.
    and i want asking how to design the code for this case sir ?? thanks for helping , i appreciate that ...

    • @vigi86
      @vigi86 7 років тому +1

      Hello Itha
      First you need the sensors, where you can measure those values (U, I). There is for example this project:
      www.engineersgarage.com/contribution/arduino-based-voltmeter
      Here are other projects from the same guy with the code bits.
      www.instructables.com/id/DIY-Amp-Hour-Meter-Arduino/
      arduinotronics.blogspot.ch/2013/06/ac-voltmeter-and-temperature-monitor.html
      Problem is, it's on the 220VAC. I hope you are an electirian. If you are not an electircian, don't play with that! It's really dangerous!
      But I guess you know what you do.
      I'm not sure what you did calculate...
      To calculate the power, the formula is quite easy:
      P = U * I --> 440W = 220V * 2A --> 0.44 kWh

    Great video; I want to use it with an arduino YUN, how can I cope with that?.
    I can not use an arduino YUN with arduino 1.0.6,
    Could you make us a video about it?? Maybe we need to use AT commands; how to configurate and connect it in that case??.

    First of all Thanks for uploading amazing video.Great job.
    Iwas wondering if you can give ne some suggestion ,
    I am working on arduino uno and want to order this shield since our SM5100 BD shield is not working with arduino UNO and also ITEAD SIM 900 is not working with arduino UNO.Because i am not able to connect any of them on Arduino's serial terminal.I am from Canada so I want to ask you if I order this shield is it gonna work properly in Canada , like will there be any issue with GSM band or this shield which you have used will work fine with the code which u have provided. because after this SMS part we will be interfacing this with sparkfun arduino weather shield.
    Thank you
