IoT-Enabled Temperature Controlled Room for Patients

The physical environment in healthcare settings is considered important for patient comfort and recovery. Among other environmental factors, room temperature is recognized as a crucial environmental factor that can significantly affect the patient’s health. Changes in room temperature can cause discomfort, making it harder for patients to heal and reducing the patient’s satisfaction with the care provided. In Malaysian hospitals, discomfort may be experienced by patients with sensitive skin due to humidity and temperature fluctuations. A device capable of measuring room temperature for sick patients is available; however, its requirement for manual monitoring complicates the maintenance of an appropriate environment. Consequently, a simple yet effective project has been designed to continuously control room temperature according to individual comfort levels. This system is designed to assist nurses and caregivers by adjusting automatically the room temperature and enabling remote monitoring through mobile applications or a web interface, implemented via the Internet of Things (IoT). The proposed system consists of a DS18B20 temperature sensor for temperature readings, along with an exhaust fan and ceiling fan or stand fan to decrease the temperature. This project uses Wemos D1 R1, a microcontroller that is based on the ESP8266, to enable IoT functionality. For the user interface, the Blynk application is utilized as the primary graphical interface for interaction with the IoT system.
