In this Arduino project, we will create a home automation system that will control home appliances using GSM module and Arduino. We will use the GSM Module SIM900A to control devices from large distances over an SMS as compared to IR based home automation. The devices will switch on and off when the GSM module … Read more
The wireless temperature sensor has been designed to measure temperature from a remote location and send it to your mobile device through the SIM900D GSM module. We use the PIC16F877A microcontroller to measure temperature using an LM35 temperature sensor. Then, we interface the microcontroller with the SIM900D GSM module to send the temperature via SMS … Read more
Send SMS using a GSM module and PIC microcontroller: This article explains how to send SMS using a GSM module and PIC microcontroller. It also covers the use of AT commands for sending and receiving SMS. I have already posted an article on GSM module interfacing with PIC microcontroller. I suggest you go through that … Read more
