So I just started a project, a #RaspberryPi #Zero2W that will read from a set of sensors through the GPIO ports.

First I tried a #DS18B20 temperature sensor. I wanted to test first before welding and the pics attached here were the solutions I could came up with. I start to love the concept of #Wago clamps, but they are expensive and quite specific to the diameters of cables and sizes.

Still, it needs a pull-up in the data pin and first I tried the internal pull-up strategy but the sensor never appears to be detected. I reworked with Wago and added the suggested resistor from power to data as an external pull-up, and it worked at first try. I am 23°C at home 

Next step is to weld the cables to size down. Ideally I want to later be able to "easily" add the second sensor to the same circuit.

The intention is that the RPi registers stuff, (now temperature), and sends the logs somewhere. Most likely another RPi in my home cluster, that stores the data history and should present any dashboard via a web server. Maybe just implementing an endpoint to explore the data from external tools.

Futures: GPS tracker?

Got this nice little present from my lovely colleagues 😍

#RaspberryPi #Zero2W

I‘m not sure yet what to do with it. Do you have any suggestions?

I got a notification from the #PiHut on Sunday and was able to get a #RaspberryPi #Zero2W that arrived this morning. I have a neat case from #SBComponents and I am getting things ready to run it #Headless.

We shall see how it all works out. One good source of info is #RaspberryTips while #JasonCannon has more general #Linux training.
