Build a Raspberry Pi door / window sensor with Reed Relais

In addition to a surveillance camera and motion sensors, information about open windows and doors is also of interest to a selfbuilt surveillance system. A check with infrared light barriers or other methods would certainly be possible, but in this case, that is much more complicated. In this tutorial, it will be shown how to easily check the status of the window with a magnetic switch ...

Configure and read out the Raspberry Pi gas sensor (MQX)

cd RaspberryPiGasSensorMQ sudo python The calibration is started automatically during initialization. It is important that the sensor is in good / fresh air as smoke / other gases would falsify the calibration. The process takes a few seconds, but the gas content can already be measured thereafter (see video). Some sensors are quite hot, but this should not be a cause for ...

Set up temperature sensors in your home with a Raspberry Pi

· You can wire the DHT22 directly to the Raspberry Pi Zero W. I used Raspberry Pi Spy''s Raspberry Pi GPIO guide to make sure I connected everything correctly. The Positive pin provides power from the Pi to the DHT22. The DHT22 runs on 3v6v, so I selected one of the 5v pins on the Raspberry Pi to provide the power. I connected the Data pin on the DHT22 to one of the Raspberry Pi …

50 der wichtigsten Raspberry Pi Sensoren und Module

· Bei dieser Aufgabenstellung eignet sich besser en abgesetzter Arduino der die Sensoren an kurzen Kabeln hält und auf Nachfrage vom PI über seinen USB Anschluß (Kabellänge am USB2 maximal 5m ohne Repeater) oder über eine Serielle RS232 an den PI mit Pegelwandler liefert, dann ist die Kabellänge auch fast unbegrenzt, nur noch abhängig von der Datenrate und der Qualität der Leitung.

50 of the most important Raspberry Pi Sensors and Components

The DS18B20 and DS18S20 represents a very simple sensor. These Raspberry Pi sensors are addressed via the socalled 1wire bus. An advantage is that many different 1wire components can be connected in series and read out by a single GPIO. However, these modules can not measure additional information such as humidity and / or air pressure. The DS18B20 is particularly suitable for outdoor …
