This main project entitled “ONE TOUCH ALARM FOR WOMEN’S SAFETY USING GSM” describes about system for women’s safety using GSM. In the light of recent outrage in Delhi which shook the nation and woke us to the safety issues for women, people are finding up in different ways to defend. Here we introduce a device which ensures the protection of women. This helps to identify protect and call on resources to help the one out of dangerous situations. Anytime you sense danger, all you had to do, is hold on the button of the device. The device consists of a microcontroller, GSM module, GPS modules. When the system activates, it tracks the place of the women using GPS (Global Positioning System) and sends emergency messages using GSM (Global System for Mobile communication), to selected contacts and the police control room. The system resembles a normal button that can be embedded in any daily wearing obstacles like footwear or something. The project includes android application and a web part to implement the embedded system effectively. Admin, user, secondary number apps, local services and an embedded system are the importance user modules in this system. The device has to be connected wirelessly with the user’s android device to implement different processes that improve safety. Automatic system calls and location tracking can be done with one-time settings in the application. Intermediate alerts and calls can be passed to local services like state police, pink police, child care, women's rights commission etc with the help of implemented system. Admin is the one who controls and manages the whole system by providing important details. The main advantage of this system is that the user does not require a manual work unlike other applications that have been developed earlier. The system does not make delays in safety of women that may end up in big tragedies. The use of sophisticated components ensures accuracy and makes it reliable.
