Fall Detection system for Elderly

Project Requirements:

The whole system is knitted around a micro programmed controller unit which takes input from various sensors and determines the necessary course of action. For these we will require various sensors and electronics like:
1. Accelerometer Sensor:to record the day to day movements and sense the change in acceleration which can happen in case of accidents.
2. Cardio Tachometer:to keep in check with the heart rate of the person sitting on the chair.
3. GPS Sensor:GPS sensor to send the exact coordinates of the person in case of any mishappening.
4. GSM Sensor:to send the message to hospital and loved ones about the location and vital information of the person for suitable course of action.

Project Implementation:

The process of the system or working of the system is very simple the network of the data is always connected to network and sensors are continuously taking the reading if the acceleration didn’t increase but the heart rate reached over threshold value call the caretakers. Now next step if acceleration passed the threshold and heart rate didn’t pass over threshold call relatives but in situations when both heart rate and acceleration passed threshold value call an ambulance. For each condition, we need to set different thresholds. Now when the calibration is done we have to test this on the real person with different scenarios
System should be tested under the following 3 conditions:
1. Person Heart rate has increased but no fall has occurred then the message to caretaker is delivered.
2. Person Heart rate is normal but fall has occurred then the message to the relative is delivered.
3. Person Heart rate has increased & fall has occurred then message to the hospital is delivered.

Software requirements:

1. Arduino IDE:software used for dumping firmware that was created for the Arduino Board to control the data feed of all the sensor and send messages
