Real-time wireless temperature measurement system of infant incubator

The internet of things (IoT) has allowed for ubiquitous measurement. Infant incubator temperature is one crucial parts that need to be measured, especially the stability and uniformity temperature. Based on interpretation IEC 60601-2-19, we proposed measurement method using IoT with message queue telemetry transport (MQTT). In 10,000 packet, result shows quality service (QoS) level 2 system highest delay, however it lowest packet loss data than other QoS. For 1 hour, can fulfill standards. Uniformity 32°C, difference point C 0.32 °C, B 0.75 °C. 36 0.27 0.79 32 °C 0.44 respectively. Moreover, Kruskal Wallis test average from M A B. It occurred because located far heater part, so colder C.
