VOICE INTEGRATED SPEED AND DIRECTION CONTROL OF DC MOTOR

It is very difficult to work in hazardous environment in many of the industries. Human can survive only certain amount of humidity, temperature, pressure, etc. Working in environments like this will cause threat to human life, so precautions should be taken against this. To overcome this huge loss voice control was developed. Due to the advancement of wireless technology, there are several connections are introduced such as GSM, Wi-Fi and Bluetooth. Each of the connection has their own unique specifications and applications. The speed control was implemented using Bluetooth technology to provide communication access from smart phone. Communication plays a major role in day today’s life and can be used as a better tool in control system. It deals with wireless communication and voice recognition and is used to control the motor speed. There are numerous techniques for speed control. Using voice as input control will reduce the manual operation. Voice recognition applications can be interfaced and speed control of DC motors can be done using the Arduino UNO microcontroller or Raspberry Pi. In addition to this IR sensor is used to sense the motor speed and in turn speed of the motor can be received via Bluetooth to the android mobile. If we control the Industrial Devices system using Speech then we can save enough time to do other sophisticated work. The voice control is highly reliable and fast. Thus the IOT makes the industrial automation much more easier.
