Easy graphing of temperatures with Raspberry Pi and NodeRed #PiDay #RaspberryPi @Raspberry_Pi

After hearing how quick and easy the graphical programming environment is for Node-Red, the WhiskeyTangoHotel blog decided to give it a try with an old Raspberry Pi 4 Model B that was ‘resting’ in a drawer.

Conclusion:  It’s easy; it’s really really easy.   Plus, there is a large user base that has created examples and libraries for just about any application you can dream up.

Node-Red is free and the install is easy and well documented on their website.  For this Node-Red experiment, they decided to graph the ambient air temperature as measured by a DS18B20 and the CPU core temperature of the Raspberry Pi 4 Model B.

Check out the implementation in the post here.
