Need some help new to this

how do i design an arduino base on sending sms or calls as soon as the pir sensor is triggered?, there is no gsm module and pir in the hardware? is it possible to do it in here? in xod? just new to this

Hello and welcome!

Technically it is possible. But would require work to implement the SMS node manually in C++. There is no out-of-the-box solutions yet. We’ll add them in nearest months.

If your PIR sensor is like mine, it is just a digital-input that goes high (true) when motion is detected, so a special node is not required.

any update on this node ?
I am to having a project that contains a sms send\receive requirement.

Hi eranak
what hardware are you using?

The one in this link

Ok i see
Simple AT commands can be sent like this.

No special node is really needed

SIM900 AT commands

  • set the SIM900 to text mode: AT+CMGF=1\r
  • send SMS to a number: AT+CMGS=PHONE_NUMBER (in international format)
  • read the first SMS from the inbox: AT+CMGR=1\r
  • read the second SMS from the inbox: AT+CMGR=2\r
  • read all SMS from the inbox: AT+CMGR=ALL\r
  • call to a number: ATDP+ PHONE_NUMBER (in international format)
  • hang up a call: ATH
  • receive an incoming call: ATA

For more information, you can check the SIM900 AT commands manual here.

Thanks, I will give it a try.
