Abstract
The study focused on the design and fabrication of a microcontroller-based smart cane with obstacle sensing, remote pulse monitoring, and automatic light system. The device was intended to provide mobility assistance and continuous monitoring fro the blind. Several tests were done to check the accuracy of all the functionalities of the device. For the obstacle sensing, the device was tested for different materials namely: wood, concrete, metal, glass, and stone. The result shows an average of 0.685% error. For the pulse monitoring accuracy test, it was tested on 12 persons and resulted to an average percent error of 6.613657552%. The GPS positioning accuracy test, on the other hand, was tested for 10 different locations and resulted to a distance tolerance of ±11 m. Upon conducting the pulse monitoring accuracy test and the GPS positioning accuracy test, it shows that the device was able to send and receive messages to and from the saved contact number or the sender. For the automatic light system, the result shows a 16.2% error from the standard illuminance value of 50 lux to switch the LED lights on. And to switch the LED lights off, the result shows a 10.9% error from the standard illuminance value of 100 lux.
