Resumo


A temperature and humidity monitoring system is to check and show the climatic
variances of the hospital’s ambience continuously as well as communicate with the professional responsible for obtaining this type of information. The study proposes a low-cost system that read both temperature and humidity through a capacitive sensor with an accuracy of ±2% relative humidity (max ±5%) and temperature precision < ±0.5 o Celsius for monitoring hospital departments such as Central Sterile Supply Department, Transfusion Agency and Surgical Center. The microcontroller receives the data from the sensor and sends it to the internet communication module, which shows the information to the user. The method used nowadays is done by manually populating tables which offer the risk of human error or data loss. The proposed system also consists of a web platform and an Android application that shows the real-time variables and generates reports of readings and alerts to unwanted variations. It could be able to modernize the process of monitoring the hospital’s departments using the Internet of Things (IoT).
