The Qwiic PIR Motion binary sensor allows you to use your Qwiic PIR (`EKMC4607112K based <https://www.sparkfun.com/products/17374>`__, `EKMB1107112 based <https://www.sparkfun.com/products/17375>`__, `firmware documentation <https://github.com/sparkfun/Qwiic_PIR>`__)

The SparkFun Qwiic PIR Motion binary sensor uses PIR sensors to detect motion. It communicates over I²C. There are two models currently available. One uses the `Panasonic EKMC4607112K sensor <https://cdn.sparkfun.com/assets/7/2/a/4/3/EKMC460711xK_Spec.pdf>`__, and the other uses the `Panasonic EKMB1107112 sensor <https://cdn.sparkfun.com/assets/c/e/8/7/5/EKMB110711x_Spec.pdf>`__.
|
||
|
|
|
||
|
|
You can configure a debounce mode to reduce noise and false detections. See :ref:`debounce-modes` for the available options.
|
||
|
|
|
||
|
|
To use the sensor, first set up an :ref:`I²C Bus <i2c>` and connect the sensor to the specified pins.

# Example configuration entry

Configuration variables:
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
- **debounce_mode** (*Optional*, enum): How the component debounces the motion sensor's signal. Must be one of ``HYBRID``, ``NATIVE``, or ``RAW``. See :ref:`debounce-modes` for details. Defaults to ``HYBRID``.
|
||
|
|
- **debounce** (*Optional*, :ref:`config-time`): Only valid when using ``NATIVE`` debounce mode. Configures the debounce time on the sensor to reduce noise and false detections. Defaults to ``1ms``.
|
||
|
|
|
||
|
|
- All other options from :ref:`Binary Sensor <config-binary_sensor>`.

Debounce Modes
|
||
|
|
**************
|
||
|
|
|
||
|
|
There are three options for ``debounce_mode``.
|
||
|
|
|
||
|
|
- ``HYBRID``:
|
||
|
|
|
||
|
|
- Use a combination of the raw sensor reading and the sensor's native event detection to determine state.
|
||
|
|
- Very reliable for detecting both object's being detected and no longer detected.
|
||
|
|
- Use binary sensor filters to reduce noise and false detections.
|
||
|
|
|
||
|
|
- ``NATIVE``:
|
||
|
|
|
||
|
|
- Use the sensor's native event detection to debounce the signal.
|
||
|
|
- Logic follows `SparkFun's reference example implementation <https://github.com/sparkfun/SparkFun_Qwiic_PIR_Arduino_Library/blob/master/examples/Example2_PrintPIRStatus/Example2_PrintPIRStatus.ino>`__.
|
||
|
|
- May be unreliable at detecting when an object is removed, especially at high debounce rates.
|
||
|
|
- Binary sensor filters are not necessary to reduce noise and false detections.
|
||
|
|
|
||
|
|
- ``RAW``:
|
||
|
|
|
||
|
|
- Use the raw state of the PIR sensor as reported by the firmware.
|
||
|
|
- May miss a very short motion detection events if ESPHome's loop time is slow.
|
||
|
|
- Use binary sensor filters to reduce noise and false detections.
