Implementation of an IoT-based Temperature and Humidity Monitoring System in the Physics Education Laboratory

Abstract

Physics laboratories require stable environments for accurate experiments, as temperature and
humidity fluctuations can affect results and damage equipment. This research aimed to implement
an Internet of Things (IoT)-based system to monitor these conditions in the FKIP UNRAM Physics
Education Laboratory. The experimental method involved designing a system using an ESP8266
microcontroller and a DHT 11 sensor, which was programmed with the Arduino IDE to send data
to the ThingSpeak platform via Wi-Fi for analysis. Over three days of testing, the system recorded
an average temperature of 30.78°C and an average relative humidity of 82.76%, successfully
revealing clear diurnal patterns and documenting inter-day environmental variability.
Implementing this IoT system proved effective for acquiring detailed and relevant ecological data,
which is crucial for ensuring the quality and validity. Future developments are suggested,
including the integration of real-time notifications, interactive dashboards, and automated trend
analysis, to further enhance laboratory management.
