FUNCTIONS

new()

Creates an object with the unique device ID *uid* and adds it to the IP Connection *ipcon*.

get_voltage()

Returns the voltage of the sensor. The value is in mV and between 0V and 45V. The resolution between 0 and 6V is about 2mV. Between 6 and 45V the resolution is about 10mV.

If you want to get the voltage periodically, it is recommended to use the :cb:`Voltage` callback and set the period with :func:`Set Voltage Callback Period`.

get_analog_value()

Returns the value as read by a 12-bit analog-to-digital converter. The value is between 0 and 4095.

.. note:: The value returned by :func:`Get Voltage` is averaged over several samples to yield less noise, while :func:`Get Analog Value` gives back raw unfiltered analog values. The only reason to use :func:`Get Analog Value` is, if you need the full resolution of the analog-to-digital converter.

If you want the analog value periodically, it is recommended to use the :cb:`Analog Value` callback and set the period with :func:`Set Analog Value Callback Period`.

set_voltage_callback_period()

Sets the period in ms with which the :cb:`Voltage` callback is triggered periodically. A value of 0 turns the callback off.

The :cb:`Voltage` callback is only triggered if the voltage has changed since the last triggering.

The default value is 0.

get_voltage_callback_period()

Returns the period as set by :func:`Set Voltage Callback Period`.

set_analog_value_callback_period()

Sets the period in ms with which the :cb:`Analog Value` callback is triggered periodically. A value of 0 turns the callback off.

The :cb:`Analog Value` callback is only triggered if the analog value has changed since the last triggering.

The default value is 0.

get_analog_value_callback_period()

Returns the period as set by :func:`Set Analog Value Callback Period`.

set_voltage_callback_threshold()

Sets the thresholds for the :cb:`Voltage Reached` callback.

The following options are possible:

.. csv-table:: :header: "Option", "Description" :widths: 10, 100

 "'x'",    "Callback is turned off"
 "'o'",    "Callback is triggered when the voltage is *outside* the min and max values"
 "'i'",    "Callback is triggered when the voltage is *inside* the min and max values"
 "'<'",    "Callback is triggered when the voltage is smaller than the min value (max is ignored)"
 "'>'",    "Callback is triggered when the voltage is greater than the min value (max is ignored)"

The default value is ('x', 0, 0).

get_voltage_callback_threshold()

Returns the threshold as set by :func:`Set Voltage Callback Threshold`.

set_analog_value_callback_threshold()

Sets the thresholds for the :cb:`Analog Value Reached` callback.

The following options are possible:

.. csv-table:: :header: "Option", "Description" :widths: 10, 100

 "'x'",    "Callback is turned off"
 "'o'",    "Callback is triggered when the analog value is *outside* the min and max values"
 "'i'",    "Callback is triggered when the analog value is *inside* the min and max values"
 "'<'",    "Callback is triggered when the analog value is smaller than the min value (max is ignored)"
 "'>'",    "Callback is triggered when the analog value is greater than the min value (max is ignored)"

The default value is ('x', 0, 0).

get_analog_value_callback_threshold()

Returns the threshold as set by :func:`Set Analog Value Callback Threshold`.

set_debounce_period()

Sets the period in ms with which the threshold callbacks

* :cb:`Voltage Reached`, * :cb:`Analog Value Reached`

are triggered, if the thresholds

* :func:`Set Voltage Callback Threshold`, * :func:`Set Analog Value Callback Threshold`

keep being reached.

The default value is 100.

get_debounce_period()

Returns the debounce period as set by :func:`Set Debounce Period`.

set_range()

Sets the measurement range. Possible ranges:

* 0: Automatically switched * 1: 0V - 6.05V, ~1.48mV resolution * 2: 0V - 10.32V, ~2.52mV resolution * 3: 0V - 36.30V, ~8.86mV resolution * 4: 0V - 45.00V, ~11.25mV resolution * 5: 0V - 3.3V, ~0.81mV resolution, new in version 2.0.3$nbsp;(Plugin)

The default measurement range is 0.

.. versionadded:: 2.0.1$nbsp;(Plugin)

get_range()

Returns the measurement range as set by :func:`Set Range`.

.. versionadded:: 2.0.1$nbsp;(Plugin)

set_averaging()

Set the length of a averaging for the voltage value.

Setting the length to 0 will turn the averaging completely off. If the averaging is off, there is more noise on the data, but the data is without delay.

The default value is 50.

.. versionadded:: 2.0.3$nbsp;(Plugin)

get_averaging()

Returns the averaging configuration as set by :func:`Set Averaging`.

.. versionadded:: 2.0.3$nbsp;(Plugin)

get_identity()

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c' or 'd'.

The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|
