Embedded Internet of Things (IoT) Enviromental Monitoring System Using Raspberry PI

Background: Measuring and monitoring the temperature and humidity levels in a computer laboratory is crucial for ensuring the safety of the facility and the comfort of those using it. The latest technology for collecting this data is the Internet of Things (IoT), which uses sensors to monitor these parameters remotely. Aim: This paper presents an IoT system that assesses the temperature and humidity levels in a computer laboratory using a Raspberry Pi single-board computer and a DHT11 sensorMethod: The major contribution of this research is it utilizes the ThingSpeak Cloud database which provide the result faster within the shortest interval time which improve the temperature and humidity values more than the traditional Message Queue Telemetry Transport (MQTT). The DHT11 sensor captures the temperature and humidity data, which is then uploaded to the servers in real-time. This allows laboratory managers and decision-makers to monitor the laboratory's condition through a web portal or a mobile application installed on their Android or iOS devices from anywhere.Results:The results show that the ThingSpeak Cloud database provides the result of the temperatureas to 31.5°C and the relative humidity 74.8%.
