Gsm Based Device Control

GSM (Global System for Mobile Communications) is the technology that lets devices connect to the mobile network for calls, SMS, and data. In Arduino and embedded projects, a GSM module acts like a “cellphone for your circuit,” allowing your system to send alerts, receive commands, track locations, and communicate remotely without Wi-Fi. This makes GSM perfect for remote monitoring, security systems, automation, and field deployments where long-distance, reliable communication is needed. #Hajimer
