AI WALKING STICK HELP BLIND PEOPLE TO WALK

AI WALKING STICK

1. Microcontroller based AI Electronic Walking Stick for Blind By- RUBY HOUSE TEAM

2. Introduction Presently, blind people use a white stick as a tool for directing them when they move or walk. Here, we develop a tool which can serve as a blind stick being more efficient and helpful than the conventional one.

3. BASIC LOGIC Five different sensors with microcontroller interface are used. IC 89s51 as the main microcontroller is used.

4. Components Microcontroller 8951 Sensors Remote Buzzer

5. LDR CONTROL UNIT BLOCK DIAGRAM

6. LDR INPUT INFRARED SENSOR INPUT REMOTE SENSOR THERMISTOR WATER SENSOR BLIND STICK WITH SENSORS

7. 8951 Microcontroller Advance version of 8051 Two types of 8951 are available- 89s51 89c51

8. Sensors used- Temperature Sensor Light Sensor Infrared Sensor Water Sensor

9. Light Sensor

10. Infrared Transmitter and Receiver In the interruption mode we use one infra red led and photodiode in pair.

11. Temperature Sensor Thermistor is used In case of high temperature, the circuit is activated and the buzzer rings.

12. Water Sensor Impedance Moisture sensors are used. For the water sensor we use two metallic plate under the stick ,when water touches on this stick then buzzer is on.

13. Remote Sensor TSOP 1738 sensor is used. Photo Detector and preamplifier in one package. Improved shielding against electric field disturbance.
