Customized print statements in the Python pass information to JEDI One.Ĭpu_temp = os.popen("vcgencmd measure_temp"). A Raspberry Pi 4’s CPU temperature will be monitored by executing the vcgencmd command within a Python script to query CPU temperature. Python is used to implement the custom data collector code for this project. Raspberry Pi is a series of small single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. With the Raspberry Pi temperature monitor selected, all you need to do is click the Add button ( 2. The custom code needs to be executable and saved in the “plugins” subdirectory where the JEDI One software is installed. Find the CPU Temperature Monitor option ( 1.) and click it to select it. Machinechat’s article, Writing plug-ins to send data to JEDI One, is a good reference and provides instructions for writing the custom code and configuring the collector plug-in. Get CPU and GPU usage on Raspberry Pi - Raspberry Pi Stack Exchange RPi-Experiences: RPi-Monitor Overview. Specifications Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC 1.8GHz 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM (depending on model) 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE Gigabit Ethernet 2 USB 3.0 ports 2 USB 2.0 ports. This project assumes Machinechat’s JEDI One IoT platform software has been installed and activated on the Raspberry Pi hardware. node-red-contrib-cpu (node) - Node-RED GL-Z 0.5. The BCM2711B0 in the Raspberry Pi 4 has four CPU cores and has a clock speed of 1.5 GHz, which at first blush doesn’t seem much quicker than the quad-core, 1.4-GHz BCM2837B0 in the Raspberry Pi 3B+. Raspberry Pi (note: a Pi 4 is used in this project but any Raspberry Pi could be used) Not implemented in this project but in addition to monitoring, SMS and email alerts can easily be configured to provide warning messages when temperature exceeds a specified threshold. Below data dashboard shows the example project of CPU temperature being monitored. Any type of code supported by the hardware can be used. The plug-in runs in the background and executes custom user code to pass data to the JEDI One. This project uses JEDI One’s custom data collector plug-in to measure and monitor a Raspberry Pi’s CPU temperature.
