2.2 Connecting the module
Connect the ultrasonic module, as seen in the following image and in the following table, to your
Raspberry Pi.
Warning! The Raspberry Pi is working, with its ARM processor core, on a voltage level of 3.3V.
But the ultrasonic distance sensor is working on a higher level.
If you are using the sensor on the Raspberry Pi without any protecon, it can lead to serious damage.
To avoid any damage you can use a voltage translator to adjust the voltage level and ensure a safe
operaon.
Therefore you can use our KY-051 voltage translator from our SensorKit X40.
In the following, we will describe how to use the sensor with the voltage translator.
