Questions & Answers on GSM Modem

What is VCC in GSM module?

SIM800L GSM Module Pinout NET is a pin where you can solder Helical Antenna provided along with the module. VCC supplies power for the module. This can be anywhere from 3.4V to 4.4 volts. Remember connecting it to 5V pin will likely destroy your module!

What is GSM GPRS module?

A GSM/GPRS Module is a device or chip that is actually responsible for the wireless communication with the GSM Network. A GSM/GPRS MODEM is device that modulates and demodulates the signals from the Wireless Network and allows internet connectivity.

How does a GSM module work?

A GSM modem or GSM module is a hardware device that uses GSM mobile telephone technology to provide a data link to a remote network. From the view of the mobile phone network, they are essentially identical to an ordinary mobile phone, including the need for a SIM to identify themselves to the network.

Why do we use GSM module?

A customised Global System for Mobile communication (GSM) module is designed for wireless radiation monitoring through Short Messaging Service (SMS). This module is able to receive serial data from radiation monitoring devices such as survey meter or area monitor and transmit the data as text SMS to a host server.

Which is the best module to use for GPRS?

Choose the right GSM GPRS module. Implement a smaller data packet (<500 bytes). Reduce the number of data transactions to save power.

How to control Arduino with GPRS and GSM?

Plug the anode wire (the red one) of power supply to the anode of LED via the breadboard, using the same method, plug the breadboard jumper wire to the cathode of LED. As we only need one relay here, we use the relay U3, which was controlled by the Arduino Pin5. There are 3 terminals for U3 relay: COM3, NC3 and NO3.

How can I Make my GPRS connection reliable?

When debugging you can connect your device over the PC interface or cloud directly via the second interface (say ethernet) and give the AT commands and check the response. This greatly helps do the debug quickly. For a reliable GSM/GPRS connection, keep your data packet small (~200 to 500 bytes).

When to turn off GPRS modem when not in use?

Put GPRS modem off when not in use and sync the data fewer times. This will save huge power. Please note, there will some power-up time to establish GPRS connection again. Use a highly efficient power supply for powering GSM/GPRS modem.
