An Efficient System for Visually Impaired by using LORA RA01

The LORA RA01 technology is offered as a useful device for visually challenged people. By giving visually impaired people a gadget that can identify barriers and warn them of potential threats in their surroundings, this system is intended to improve their mobility and independence. The LORA RA01 technology is the best option for this application since it has minimal power requirements and long-range communication capabilities. A wearable device with a range sensor and a LORA RA01 module, which connects to a centralised server, make up the proposed system. The server analyses the data from the range sensor and uses a haptic feedback method to provide the user feedback in real-time. The system has undergone testing in a variety of settings and has proven to be trustworthy in its ability to identify barriers and give the user prompt feedback. Overall, this approach has a lot of promise for enhancing the mobility and security of people who are blind.
