Paper is based upon security access and control system using RFID and Arduino with GSM module. Some of the sensors are used like PIR, LPG for leakage detection. Security access system is very convenient to use at home, office and commercial buildings.Grewal Kaushal...
Similar to the SIM800L module, the SIM900A breakout board has eight pinouts. They don’t have labels so allow me to provide them for you: The primary difference between theSIM900A and the SIM800L is that this board doesn’t have Bluetooth and FM support. But the AT command set for ...

To access a network, you must have a subscription with a mobile phone operator (either prepaid or contract), a GSM compliant device like the GSM shield or mobile phone, and a Subscriber Identity Module (SIM) card. The network operator provides the SIM card, which contains information like ...
GSM_AUTOBAUD_MIN, GSM_AUTOBAUD_MAX);). While very useful when initially connecting to a module and doing tests, these shouldNOTbe used in any sort of production code. Once you've established communication with the module, set the baud rate using thesetBaud(#)function and stick with that...
