GSM Module Interfacing with 8051 Microcontroller

Project Information

By utilizing microcontrollers as an alternative to PCs, we can establish interaction between a GSM module and an LCD, simplifying the process of interfacing GSM with an AT89S52 microcontroller. This interface involves sending AT commands from the microcontroller, receiving responses from the GSM module, and displaying them on an LCD. Communication between the microcontroller and the GSM module is achieved through the microcontroller’s serial port, utilizing PIN 10 (RXD) and PIN 11 (TXD).
