A safety device which sends the time and location of the user to a pre-set phone number.
The idea is to make an add-on for a watch/any wearable which when triggered on by a button, sends the time and location of the user to the nearest police station and a set of emergency contacts with the help of a GSM/ GPS module, asking for help. The add-on unit will be controlled by a unit that comprises of the development board (eg: Arduino Uno) and the GSM/GPS module, which can be placed in the bag of the user. These two units can be connected via bluetooth.
A prototype was developed for this project which sent out a buzzer alarm, and an emergency message to a preset mobile phone when triggered by a button.The circuit was successfully executed. On activation the location received by the GPS Module was transferred to the GSM Module which was sent as an SMS to the pre programmed phone number.The buzzer was also activated at the same time.
