What is GSM based home automation?
The analysis and implementation of the home automation technology using Global System for Mobile Communication (GSM) modem to control home appliances such as light, conditional system, and security system via Short Message Service (SMS) text messages is presented in this paper.
How can I receive SMS using GSM module with PIC microcontroller?
During the initialization of the module , we send AT+CNMI=1,2,0,0,0 to the modem. This command force the gsm module to send “receive SMS” string on UART transmit pin of the GSM module and it will receive on RX pin of PIC microcontroller.

What is the advantage of GSM?
Advantages of GSM : No roaming charges on International calls. Worldwide connectivity and extensive coverage. SAIC and DAIC techniques used in GSM provide very high transmission quality. The phone works based on the SIM card so that it is easy to change the different varieties of phones by users.
Is GSM module a microcontroller?
The circuit of interfacing GSM to AT89C51 microcontroller mainly consists of GSM modem and 8051 family microcontroller. GSM has RS232 interface for serial communication. In between the GSM module and the microcontroller MAX232 IC is connected. MAX232 IC is used for converting the logic levels.
What are the disadvantages of GSM?
The following are some disadvantages of GSM:
- Electronic interference. Because GSM uses a pulse-transmission technology, it is known to interfere with electronics like hearing aids.
- Bandwidth lag.
- Limited rate of data transfer.
- Repeaters.
What can I do with a 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.
What is GSM in IoT?
Quick definition: GSM stands for Global System for Mobile Communications. It’s a standard that specifies how 2G (second generation) cellular networks operate. GSM was a significant improvement over the first generation of cellular networks and represented a transition from analog to digital telecommunications.
