Hi Adam
According to the datasheet for the sensor, the output voltage can be between 0 and 5V. As the maximum input voltage on the ADC DAC Pi is 3.3V you will need to use a voltage divider between the sensor and the ADC input to reduce the maximum voltage down to a safe level.
We have a resistor divider calculator at
https://www.abelectronics.co.uk/tools/resistor-voltage-divider which you can use to find suitable resistor values. If you use a 1K resistor for R1 and a 1.8K resistor for R2 that would reduce 5V down to 3.21V making it safe to connect to the ADC input.
Using the above resistor values, in your python code, you will need to multiply the ADC voltage by 1.556 to get the correct voltage reading from your sensor.
