In this case, an external 10k resistor should be wired for each sensor?
In the sample code on the link below, is the "INPUT_PULLUP" setting only be used if there is no external 10k resistor wired to the sensor?

2021-02-19 13:42:12 The principles of these two sensors are similar, the pull-up resistor will affect their measuring distance, you can add them appropriately according to your needs. When there is no pull-up resistor, use "INPUT_PULLUP" 347945801
