Abstract:

This article describes the design of a system that implements the temperature and humidity monitoring function of the incubators for newborns. The design circuit will contain a resistive temperature sensor connected in a bridge configuration and a capacitive humidity sensor. For the data to be read by the microcontroller, a signal conditioning block will be designed to amplify the outputs of the two sensors and bring them into the input range of the analog-to-digital converter. USB heating elements will be used to adjust the temperature. An 8-bit ATMEL family microcontroller will be used and the program will be developed using the Code Vision AVR compiler. In order to validate the data, a comparison will be made between the monitoring system described above and a LIBELIUM Smart Environment plate containing calibrated sensors that provide very good temperature and humidity values based on a set sampling frequency. The development environment for the LIBELIUM is ARDUINO, which will send the data over the Wi-Fi network using the MQTT protocol to a SQL database with a Grafana web interface for viewing. In order to alert medical staff to exceeding the range of temperature or humidity values, I will also implement a code to send email alerts from the Grafana web interface that communicates with LIBELIUM Smart Environment.
