RPC1507 Datasheet If active-high OUT polarity is selected, the pulses will only appear if there is a pull-up resistor in place and the fluid is not present (no detection, low output), or, if there is a pull-down resistor and the output is active (high output). If the sensor is wired to a microprocessor as shown in Figure 3-3, the microprocessor can reconfigure the load resistor to either ground or Vcc depending on the output state of the QT114, so that the pulses are evident in either state with either POL setting.
