Smart blind stick with voice module

In this paper we propose a new device which assists the blind people for their daily activities without depending on other people. This device will improve the confident level of the blind people. This device is used to detect the objects like solids or liquids in front of them. This proposed system uses the arduino controller. This system is detect the objects with in 90 cm. Ultra sonic sensor is fixed in the stick end. This sensor senses the objects and inform to the blind people through voice message. When the voice message is received from this device, the blind people can detect the objects. This system consists of three ultrasonic sensors such as front, left and right. This system is mainly used to identify all type of objects on the path. This proposed device is also used to identify the blind people location and send the information to the concerned people with the help of GSM. This system is executed based upon ultrasonic sensor.
