Convert High voltage output ( 15V ) to 5 V
Assuming this configuration: -

Your output voltage will be from about 1 volt to about 13 or 14 volts so, if you use a 20 kohm to 10 kohm potential divider like this (on each output signal): -

The output voltage will be operate between about 0.3 volts to about 4.5 volts and be compatible with most MCU inputs. The divider will also present an output impedance of about 6 kohm so if the supply voltage (15 volts) to the sensor were raised a bit, the output impedance would prevent a serious over-voltage event happening to the MCU input by substantially current limiting the current into the MCU pin.
