Linear Magnetic Hall Sensor
In contrast to the Arduino, the Raspberry Pi has no analog inputs and no ADC (analog digital converter) is
integrated in the chip of the Raspberry Pis. This limits the Raspberry Pi if you want to use sensors that do
not output digital values, but should be a connuous, variable value (example: potenometer -> other
posion = dierent voltage value).
To avoid this problem, there is our KY-053 module, with 16 bit accurate ADC, which you can use on the
Raspberry to expand it by 4 analog inputs. This is connected via I2C to the Raspberry Pi, takes over the
analog measurement and passes the value digitally to the Raspberry Pi.
Therefore we recommend to connect the KY-053 module with the ADC in between for analog sensors.
