Details in thedocumentation.

Use

  • Connection of sensor output to an analog-to-digital converter (e.g. built in microcontroller or analog input in Arduino).
  • Connection via comparator directly to I/O pins.
  • Using the internal comparator built in some microcontrollers.
The manufacturer has preparedlibraries forAVR familymicrocontrollersand forArduinousers, making it easier to operatethe sensor.
