Sensors: input devices for documentation, control, inventory, etc.

Here you will find a selection of sensors. Please pay attention to the way the measured values ​​are output. The analog output can be read directly by an Arduino. For RaspBerry Pi, all I²C-Bus outputs can be read directly. 

Sensors have either analog or digital outputs. With an analog output, the sensor cannot be connected directly to a RaspBerry Pi. For this you need an analogue-digital converter / analogue-digital converter (ADW, ADC) which converts the signal (a voltage between 0 to 42 volts) into a digital value and passes it on to the computer via the I²C bus gives.
