VOICE-ACCESSIBLE IOT HYDROPONIC MONITORING FOR THE VISUALLY IMPAIRED INDIVIDUAL

Abstract

This paper presents the development of a voice-accessible IoT hydroponic monitoring system, specifically designed for individuals with visual impairments. Visually impaired individuals often face challenges in managing hydroponic systems due to the reliance on visual indicators for monitoring parameters such as water levels, nutrient concentrations, and plant health. The lack of accessible tools to interpret these parameters hinders their active participation in modern agriculture. To address these limitations, the integration of sustainable hydroponics with IoT technologies in this project offers an inclusive and empowering experience. The system's hardware comprises ESP32 microcontrollers that collect data and manage devices, alongside water level and TDS sensors to assess critical parameters such as water availability and nutrient concentration. Environmental sensors monitor temperature and humidity to support precise climate regulation, while automatic water pumps manage irrigation, promoting optimal plant growth with minimal operator intervention. A key component of the system is a website designed for real-time data reporting that is accessible to blind individuals. This allows users to remotely access vital agricultural data and understand their system’s performance. To further enhance accessibility, the web interface integrates voice-assistive technology, delivering audio feedback on essential parameters such as water levels, fertilizer concentration, temperature, humidity, and plant development stages. The voice-activated interface empowers blind users to manage their hydroponic systems independently through intuitive audio commands. This initiative, funded by the Sarawak Branch of the Society of the Blind, Malaysia, in collaboration with Politeknik Kuching and supported by Sarawak's Information Technology and Communication Department, highlights the potential of IoT to bridge accessibility gaps. Beyond technological innovation, the project equips visually impaired individuals with practical skills, promotes autonomy, and creates sustainable income opportunities. It emphasizes the importance of collaborative efforts in developing inclusive, community-centered solutions. By leveraging IoT and voice-accessible technologies, the initiative not only removes barriers but also fosters social inclusion and demonstrates the transformative power of technology in agriculture and beyond.
