Barometer ========= **Mesure the atmospheric pressure** Sensor to compute the atmopsheric pressure, using the ISA model: - https://en.wikipedia.org/wiki/International_Standard_Atmosphere - http://en.wikipedia.org/wiki/Atmospheric_pressure The current implementation is only correct in the Troposphere, i.e. for an altitude less than 11000m .. cssclass:: properties morse-section Configuration parameters for Barometer -------------------------------------- You can set these properties in your scripts with ``.properties(=..., =...)``. - ``ReferencePressure`` (float, default: ``101325``) Reference pressue, in Pascal. By default, the standard pressure at the sea level .. cssclass:: fields morse-section Data fields ----------- This sensor exports these datafields at each simulation step: - ``timestamp`` (float, initial value: ``0.0``) number of seconds in simulated time - ``pressure`` (float, initial value: ``0.0``) Pressure in Pa *Interface support:* - :tag:`yarp` as yarp::Bottle (:py:mod:`morse.middleware.yarp_datastream.YarpPublisher`) - :tag:`socket` as straight JSON serialization (:py:mod:`morse.middleware.socket_datastream.SocketPublisher`) - :tag:`text` as key = value format with timestamp and index value (:py:mod:`morse.middleware.text_datastream.Publisher`) - :tag:`moos` as StringPublisher (:py:mod:`morse.middleware.moos.abstract_moos.StringPublisher`) .. cssclass:: services morse-section Services for Barometer ---------------------- - ``get_properties()`` (blocking) Returns the properties of a component. - Return value a dictionary of the current component's properties - ``get_local_data()`` (blocking) Returns the current data stored in the sensor. - Return value a dictionary of the current sensor's data - ``set_property(prop_name, prop_val)`` (blocking) Modify one property on a component - Parameters - ``prop_name``: the name of the property to modify (as shown the documentation) - ``prop_val``: the new value of the property. Note that there is no checking about the type of the value so be careful - Return value nothing - ``get_configurations()`` (blocking) Returns the configurations of a component (parsed from the properties). - Return value a dictionary of the current component's configurations .. cssclass:: examples morse-section Examples -------- The following examples show how to use this component in a *Builder* script: .. code-block:: python from morse.builder import * # adds a default robot (the MORSE mascott!) robot = Morsy() # creates a new instance of the sensor barometer = Barometer() # place your component at the correct location barometer.translate(, , ) barometer.rotate(, , ) robot.append(barometer) # define one or several communication interface, like 'socket' barometer.add_interface() env = Environment('empty') .. cssclass:: files morse-section Other sources of examples +++++++++++++++++++++++++ - `Source code <../../_modules/morse/sensors/barometer.html>`_ - `Unit-test <../../_modules/base/barometer_testing.html>`_ *(This page has been auto-generated from MORSE module morse.sensors.barometer.)*
