AKOi Heart, IoT AKOi Heart is a product that attaches to the diapers of socially vulnerable groups such as babies, the elderly, people with disabilities, and patients, and notifies the caregiver’s smartphone app in real time when urine is detected. It helps prevent skin rash and infection by alerting you to prompt detection of urine. AKOi Hub connects with AKOi Heart via 2.4G and 5GHz WiFi communication, and it provides information on the surrounding temperature and humidity through AWS (Amazon Web Services). If the surrounding environment changes and goes outside the set range, the smartphone app will immediately notify you with an alert. Additionally, the IoT AKOi Call Device and the DEAF AKOi Call Device are devices that notify the guardian of call information in real time, and they were selected as a pro-elderly innovative product by the Seongnam Senior Innovation Center.
