How does a GPRS module work?
GPRS is classed as being a packet switched network whereby radio resources are used only when users are actually sending or receiving data. Rather than dedicating a radio channel to a mobile data user for a fixed period of time, the available radio resource can be concurrently shared between several users.
What is the advantage of GPRS over GSM?
An advantage of GPRS over GSM is that GPRS has a much higher data transmission speed. GPRS can be used as the bearer of SMS. If SMS over GPRS is used, an SMS transmission speed of about 30 SMS messages per minute may be achieved. This is much faster than SMS over GSM.
How to send data from GPRS to GSM module?
Process of Sending Data from GPRS of GSM Module is easy. Here in this project, we are sending some string or words to the server by typing using keypad. Same string or word will appear over the LCD, then press D/OK to send the input string to the server.
How does GSM module connect to web server?
When we finish our text entering then we press D button on the keypad to send the data to web server. The GSM module connects to the web server by using the information defined in the code such as public and private keys. GSM send the data on the web server which we can check by opening the web server.
How does GSM send data from a sensor?
Now the module’s IP address is displayed on the LCD and the gsm_send_data function is called. This sends the data from the sensor. The first time the function is called, the sensor has not been read, so the values are t (temperature) = 00 and h (humidity) = 00.
How to send data from Arduino to GSM module?
Circuit diagram for sending data to a web server using Arduino and gsm module is given below: Circuit Diagram for sending data from gsm module to a web server LCD pin R/S to Arduino pin A0. R/W to ground. LCD pin Enable to Arduino pin A1. LCD pin D4 to Arduino pin A2. LCD pin D5 to Arduino pin A3.
