The main aim of this project is to design and construct a system with which gestures are given through MEMS sensors which are converted to voices using Bluetooth technology. It is very use full for paralysis, Deaf and Dumb people to express their needs by using simple hand gesture using MEMS technology. This glove consists of heartbeat and temperature sensors to monitor the health parameters of the person and will be upload into the thingspeak cloud along with date and time using ESP8266 WI-FI module. If the system detects high temperature or high heartrate, it will give the buzzer for alerts. The whole system is controlled by Arduino UNO. MEMS sensor, Pulse oximeter, MEMS, Buzzer, LCD display, ESP8266 WI-FI and HC-05 Bluetooth module is interfaced to Arduino. All these components are placed on the glove which is operated with 5VDC power. User wear this glove to his/her hand. By using simple hand gesture, user will express their needs like water, food…over Bluetooth. The Arduino will read the health parameters through sensor will be upload into the thingspeak cloud along with date and time using ESP8266 Wi-Fi and also activate the Buzzer when the temperature and heartrate cross the set limit. The status of the project will display on LCD. To achieve this task Arduino UNO microcontroller loaded program written in embedded C language.

 

The main objectives of the project are:

1. Simple gestures movement-based voice conversion.
2. Gesture movement using MEMS technology.
3. Health monitoring using heartbeat and temperature sensor.
4. Using Bluetooth application to announce the voice.
5. IoT based wireless monitoring of person health parameters.
6. High temperature and heartrate alert using Buzzer.
7. Visible alerts using LCD display.
