Smart emergency response system

The Internet of Things is one of the trending technologies wherein connecting any device to the Internet and control power to any appliance and in addition possess capability of connecting those appliances to each other in creating a network. In this work, a WiFi enabled micro-controller is interfaced with few sensors like ADXL335, a 3-axis accelerometer for sensing tilt of the object, motion, vibration or shock, Pulse Sensor to give live heart data rate, DHT11 Sensor to sense ambient temperature and humidity. The number of sensors is scalable but constrained depending on WiFi enabled micro-controller capability and permissible limits have been set for each of these sensors in case of the emergency response. The GPS module is also interfaced with the WiFi enabled micro-controller for positioning and tracking purposes. For monitoring purpose, the collected data from each of these sensors is displayed using I2C 128×64 OLED display connected to the micro-controller development board. The WiFi enabled micro-controller is connected to the Thinger.io, a cloud platform used for storage and visualization purposes. The endpoints feature on Thinger.io platform facilitate to send email, push the data to the external services which are particularly useful while using third party services. The free web based service IFTTT is used to send SMS having full emergency response profile to the responder whenever emergency condition occurs.
