2. In the recent years, Health Care has grown rapidly through the
recent development in the Science and Technology.
Development in the Wireless Sensing Technology has been great
boon to the Health care industry.
Falls are a great cause of fear and lack of confidence and
independence among older people. Sometimes falls may
even lead to death.
Falls of the elderly always lead to serious health issues as the
decline of their physical fitness. Fracture is the most common
injury in fall of an elderly and there is also a certain possibility to
get coma, brain trauma, and paralysis.

Introduction
3. Abstract
Unobserved human falls can be dangerous and can badly affect health.
Falls can cause loss of independence and fear among the older people.
In most fall events external support is essential to avoid major
consequences.
Thus, the ability to automatically detect these fall events could help
minimizing the response time and therefore prevents the victim from
having serious injuries.
So minimize this problem we propose a fall detection system by
using MPU6050 sensor.
The output will be come to mobile as a SMS.

4. Objectives
• To provide unconditional care to the senior citizen and to the
patients has some problems which can make them faint.
• To reduce the time delay between fall event and rescue time.
• To get assistance immediately from the Relations after we fall ,
through SMS notification.
• The ultimate goal of the detector system is to realize a fall event and
manage to notify an assistant immediately.
4
5. Problem Identification
Elderly people have more fear while walking alone anywhere .
More number of sensors are used to detect fall.
Drunken people were fall on the road and they were hard to identify.
Early assistance may reduce the risk of problems. Hence this Fall
detection system would be great use for the mankind.
Cameras are distributed at limited space to offer pictures or videos
of human activities to implement fall detection algorithm.
5
6. Scope of the Project
Only one sensor is used to detect the fall of elderly people.
It reduce the time delay between fall event and rescue time.
It is a wearable device and it been light weight.
Whenever we fall, the system will send the location immediately
through SMS immediately.
System will be designed to be compact and user friendly.

12. Description Of Component
NodeMCU ESP8266:
Node MCU is an open source platform.
It utilizes the ESP8266 Wi-Fi module, facilitating rapid
prototyping and development.
Here, in our project this microcontroller fetch the data from the
sensors and it transfer to the mobile notification.
The supply of input voltage is given by the 3.7V Rechargeable
battery.

13. Description Of Component
MPU6050 Sensor:
MPU stands for “Motion processing Unit”. The MPU6050 sensor
module is used to measure acceleration, velocity, orientation,
displacement, and many other motion-related parameters.
The MPU6050 module is small in size and has low power
consumption, high repetition, high shock tolerance, and low user
price points.
In this project, it is used to find the vibration of the objects,
whether they have fall down or not.

14. 3.7V Rechargeable Battery:
The battery is used for the power supply to the circuit.
It is eco-friendly.
Connecting Wires:
These are electric wires which is used to connect two points in a
circuit.
In this project, the wire connections are done by soldering.

Description Of Component
15. Mobile or Laptop:
The output data can be visualized in mobile or laptop.
The notification will be send to the mobile number or Email id
about the subject status.

17. • In conclusion, our project aimed to explore the feasibility and
effectiveness of using MPU6050 sensor to detect the falls of a
person. MPU6050 sensors proved to be reliable in detecting both
accidental and physiological falls. The accuracy of fall detection
was significantly influenced by sensor placement and calibration.
