Aim
The aim of the project is to alert the blind persons if there is an object
in their pathway.
Problem statement
Blind people can’t easily recognize obstacles or stairs while using normal blind stick. The blind traveler should depend on any other guide like blind cane , people information , trained dogs, etc.By this their problem will overcome using Blind Stick.
Material used
Input: IR Proximity Sensor
Brain: TinkerSpace Sensor Board
Output: Buzzer
Battery: Lithium-ion rechargeable battery
Component description
IR PROXIMITY SENSOR
The function of IR Proximity sensor is to detect the objects within 20CM and send the signal to the Brain unit (TinkerSpace board).
BUZZER
The function of the Buzzer is used to produce alert/alarm sound
TinkerSpace Sensor Board
TinkerSpace board acts as brain of this project, its function is to monitor IR Proximity Sensors and control the BUZZER.
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case – 1: When an object is detected near the blind person, the IR proximity sensor (input) turns ON and sends signal 1 to the TinkerSpace sensor board (brain). The sensor board turns ON the buzzer (output).
Case – 2: When no object is detected, the IR proximity sensor turns OFF. Hence the sensor board turns OFF the buzzer.
IR proximity sensor ON —> Buzzer ON
IR proximity sensor OFF —> Buzzer OFF
Circuit Design (DesignSpace)
Step 1: Connect IR PROXIMITY SENSOR to input
Step 2: Connect BUZZER to output 1
Step 3: Select DIRECT MODE (D) in Sensor board
Step 4: Connect supply and test project.
