I was concerned about the temperature of the CPU of my RPI.
In this hot summer in Rome, temperature is often above 40 degrees and I don’t want to burn my PI.
I decided to give a try and develop an IoT app that measure the temperature of the CPU and send it to a Cloud Hub (I have used IBM Watson IoT) in order to visualize it and analyze it.
The application running on the device has been developed using NodeRED. It gathers the temperature every 10 sec. and send a msg to the IBM Cloud, using the dedicated node provided by NodeRED.
It is easy.
Then I have directed the flow of one ventilator towards the case of the PI and… it works. It is really cooled down
quickly.
See the result:
