Optimization and Development of Raspberry Pi 4 Model B for the Internet of Things

The Internet of Things (IoT) in this manuscript is how to utilize the Raspberry Pi 4 Model B, which has reliable specifications in becoming a mini-PC function; as a mini processor that has powerful capabilities, the Raspberry Pi 4 model B was developed from previous versions, such as power supply models and graphics or monitor ports with mini HDMI ports and also on the development side of the Python 3 programming language. Raspberry Pi can also be developed with Radio Frequency devices such as ZigBee and LoRa modules. Raspberry Pi 4 B can also be IoT sources that can provide specific and real-time information, for example, CPU temperature information when the Raspberry Pi 4 is operating. Cloud servers or application servers such as The Things Network or Thingspeak MatLab are used as real-time data information in graphs or images that can be viewed on various platforms utilizing a Web desktop or Mobile with an internet connection. From the analysis results, the Raspberry Pi 4 CPU has a temperature range of 40-55 degrees Celsius.
