A secure health monitoring system connects patients with medical organisations using the Internet of Things and cloud infrastructure. Sensors capture vital signals from an individual, which are then processed and encrypted using the Advanced Encryption Standard algorithm directly on a NodeMCU microcontroller. This microcontroller also provides wireless connectivity to transmit the encrypted health data securely to the cloud for storage. Authorised medical specialists can visualise these private health records in real time, provided they supply the appropriate decryption credentials. To support rapid intervention, the setup automatically detects abnormal readings and issues email alerts to designated patient relatives or the coordinating healthcare specialist. The overall design emphasises privacy, data protection, and continuous real-time connectivity between patients and healthcare providers.
Remote health monitoring allows patients to be observed outside clinical settings without compromising data privacy. By encrypting sensitive records before transmission and issuing immediate alerts when vital signs deviate from safe thresholds, such systems protect personal information while enabling faster responses to emerging medical issues.
The system enables remote patient monitoring applications for healthcare organisations and clinical specialists seeking secure, wireless telemetry. Because the abstract describes an implementation built on a NodeMCU microcontroller with email alerting, the work appears to be at an early-stage prototype level, requiring further development, system integration, and testing before commercial use.

This paper presents a secure IoT-based health monitoring system that shortens the distance between a patient and the relevant medical organization. Vital signals captured from sensors are processed and encrypted using AES (Advanced Encryption Standard) algorithm before sending to the cloud for storage. A Node MCU microcontroller is utilized to carry out the processing and encryption functions, and for providing connectivity to the cloud over WiFi. In addition, a medical specialist can visualize the private health data in real-time only after providing decryption credentials. Moreover, the proposed system provides an alert by sending an email to some patient relatives or coordinating specialist if vital signs are outside the normal rates. The proposed system provides privacy, security, and real-time connectivity for private health data records.
