So this DIY project reads data from GPIO (General Purpose IN/OUT) pins, in this case temperature recorded on TMP-36 Sensor, and plots it using real time streaming using the Plotly Python API! Pretty cool? We think, it is!

This is what it will look like, once you’re done.

So let’s get started.

You will need an RPI, MCP3008 DIP package ADC converter chip, TMP-36 Analog temperature sensor, breadboard and hook up wire and depending if you want to solder stuff or not, you can get RPI Proto Shield or Pi Cobbler, respectively.

And of course, an account on Plot.ly!

You start with enabling the SSH on your raspberry Pi and setup the software given in the link below. Once you’re done, you can start putting the hardware together. This is what you’ll get.

You can again, find the pin diagrams in the source link.

You need the MCP3008 chip to read analog data from the RPI. You can connect it to the breadboard and Pi Cobbler it! And, you’re done.

It really is that simple. Head over to the link given below and make your own real time graph.
