The Intelligent Navigation System is a powerful tool helpful for visually impaired persons in achieving fully independent navigation for those with vision loss and blindness to move freely, and safely with less cost implication.This paper is made up of three sections, which are the Sensory Unit, the Wireless AC Detector Unit, and the Retrieval Unit (RF Unit). The Sensory Unit comprises of three ultrasonic sensors, fire sensor, smoke sensor, and water sensor are all mounted in a box close to the tip of the stick and receives their power supply from the Arduino UNO board, acting as the brain of the device. The AC Wireless Detector uses a 555 Timer IC with a buzzer and an LED as indicators connected to a 9volts dc battery. The receiver and transmitter module are connected to their respective ICs and antennas with a 9volts battery supply to each of them separately. All the sensors performed as expected with the ultrasonic taking readings from 0 – 70cm and at exactly 50cm the ultrasonic sensors detected obstacles in their respective directions. The water sensor taking its reading from 3-5cm of depth. At 3cm the water level sensor detected water. The AC wireless detector buzzed as the LED turned on as it approached a livewire within the range of 1 – 50cm in its direction. Specifically, at 30cm the wireless detector detected a livewire
