This project is designed to guide a visually impaired person to walk and avoid bumping into obstacles. Low cost ultrasonic rangefinders along with a microcontroller is used to measure the distance to obstacles and if they are close enough provide a feedback to the user in form of beeps or vibrations.
The project is made on a small single layer PCB. The sensors are not mounted on the PCB but they are mounted on front of the stick and connected to the main board using wires. All the parts of project PCB is shown in the image below.

@Uttam Dutta,
Thank you 🙂
Awesome Project Avinash. Congratulations . Very Useful
@Jayaprakash
Thank you
Sir we are doing your project as our science exhibition project so I need your help in making the prototype
plz send me HEX file of this project
My cousins
urgently need two sensing walking sticks as they are visually impaired. Can you please inform me where these sticks are available for purchase and what is the cost of each stick. G N Rao
@Mr NAGESWARA RAO,
Sorry, but I have NOT manufactured these sticks on commercial scale. I just made prototype circuit and programming.

Hi Avinash. Can I get to see the video tutorial of the making of this project?
TIA
Hello friend I want this ultra sonic stick please send price details
hi,this post is quite useful.Please help me with this. I am working on obstacle masurement and i have to connect 4 hc sr04 ultrasonic range finder with Microcontroller At89S52. please provie the circuit diagram for it. Please provide as soon as possible.

hello,
sir i made this circuit but my sonar sensors are not any obstacle
pls suggest me whether may be a problem
i done all connection same as there shown in your PCB layout
and i used your HEX file as you uploaded to burn my microcontroller
but my project is not working
Can you please tell me the estimate cost of your design?
How to make the prototype please explain sir
@Ansuman,
Can you see the Read More link on the post?
What you think it does? turns on the shower of your bathroom?
Where can we get the model?
Is this item (smart cane) is being marketed, if so where. Thank you
plz give us program for smart blind walking stick using pic18f4520 with following features like ldr moisture sensor and ultrasonic sensor…plz give us the program
We need around 1000 smart sticks for blind for a ngo
Kindly quote your rate & availability.
