Obstacle detector for blind using IR sensor


 

Components required :
1.5 sensors(LDR )
2.Wooden stick
3.Connecting wires
4.Adapter
5.Black tape
6.Screws
7.DC jack
8.In case of 9v battery snap is required
9. buzzers
10.Batteries (5/9 V)
Procedure
1.Take a wooden stick of 80-90 cm and fix 3 sensors at the end  of the  stick .
2. Fix  the remaining 2  sensors on the body stick for left and right detection.
3. Connect all the positive terminal of sensors together( same  for negative terminal ) so that only two wires can connect to battery.
4.Output terminals of 3 sensors  which are fixed at top are connected altogether  to the positive terminal of buzzer 1 and  the negative terminals should be connected  to the  negative terminal of battery.

5. Same connection is repeated for the remaining two sensors to buzzer 2.
5. Supply can be given  using battery or adapter. You can vary your sensor's potentiometer according to your requirement.

Now your detector is ready.
