➔The risk of institutions in looking after the people has increased these days.
➔The missing complaints in old age homes , kindergarten have increased.
➔The death rate due to injuries or accidents have increased .

➔NodeMCU ESP8266 ESP-12E:
The ESP8266 Integrates 802.11b/g/n Wi-Fi transceiver, so it can not only connect to a Wi-Fi network and Interact with the Internet, but it can also set up a network of its own, allowing other devices to connect directly to it.
➔GPS module Neo 6m:
It a battery for power backup and EEPROM for storing configuration settings. A ground based receiver or GPS module can calculate its position and time.
➔FALL DETECTION-MPU6050 Accelerometer:
MPU6050 is a Micro Electro-mechanical system (MEMS), it consists of three-axis accelerometer and three-axis gyroscope. It helps us to measure velocity, orientation, acceleration, displacement and other motion like features.

➔The development board equips the ESP-12E module containing ESP8266 chip having Tensilica Xtensa® 32-bit LX106 RISC microprocessor.
➔It operates at 80 to 160 MHz adjustable clock frequency and supports RTOS.
➔The ESP8266 NodeMCU has total 17 GPIO pins. Digital I/O Pins (DIO): 16,Analog Input Pins (ADC): 1,2 UART interfaces,4 PWM outputs, SPI, I2C & I2S interface.
➔The ESP8266’s pin have multiplexing feature (Multiple peripherals multiplexed on a single GPIO pin). Meaning a single GPIO pin can act as PWM/UART/SPI.
➔There’s also 128 KB RAM and 4MB of Flash memory.
➔The ESP8266 Integrates 802.11b/g/n HT40 Wi-Fi transceiver.
➔The operating voltage range of ESP8266 is 3V to 3.6V, 80mA Operating Current,20 µA during Sleep Mode.
➔The ESP8266 NodeMCU features two buttons. One marked as RST located on the top left corner is the Reset button, used to reset the ESP8266 chip. The other FLASH button on the bottom left corner is the download button,used while upgrading firmware.
➔The board also has a LED indicator which is user programmable and is connected to the D0 pin of the board.

●The NEO-6M GPS module is a well-performing complete GPS receiver with a built-in 25 x 25 x 4mm ceramic antenna, which provides a strong satellite search capability. With the power and signal indicators, you can monitor the status of the module.
● Thanks to the data backup battery, the module can save the data when the main power is shut down accidentally.
● This module is one of popular GPS modules on the market and is also cheap to buy. The location data provided by it is accurate enough to satisfy most applications.
