Configure and read out the Raspberry Pi gas sensor (MQ-X)

Felix - 17. March 2017

Sensors are necessary to detect the components of the air. These are used e.g. in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown. Thus, e.g. smoke detectors or air […]

Top 10 Raspberry Pi 3 Cases (with fan, screen, …)

Felix - 22. February 2016

All Raspberry Pi models are delivered without a case. But to protect your Pi it is recommended to use one and additionally it is nice to look at. There are so many really nice cases with fans or integrated touchscreens. You might ask which is the best Raspberry Pi case and which are most useful […]

Let Raspberry Pi’s communicate with each other per 433MHz wireless signals

Felix - 26. October 2015

Maybe some of you thought about how to let some RaspberryPi’s communicate with each other wirelessly. For this purpose small 433MHz modules are ideal, which are already available for a few bucks. Therefore in this tutorial I want to show how two (or more) RaspberryPi’s can “talk” with each other. But do not worry, if […]
