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
Configuration parameters for Barometer¶
You can set these properties in your scripts with <component>.properties(<property1>=..., <property2>=...)
.
ReferencePressure
(float, default:101325
)Reference pressue, in Pascal. By default, the standard pressure at the sea level
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:
text
as key = value format with timestamp and index value (morse.middleware.text_datastream.Publisher
)socket
as straight JSON serialization (morse.middleware.socket_datastream.SocketPublisher
)yarp
as yarp::Bottle (morse.middleware.yarp_datastream.YarpPublisher
)
Services for Barometer¶
get_properties()
(blocking)Returns the properties of a component.
Return value
a dictionary of the current component’s properties
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_local_data()
(blocking)Returns the current data stored in the sensor.
Return value
a dictionary of the current sensor’s data
get_configurations()
(blocking)Returns the configurations of a component (parsed from the properties).
Return value
a dictionary of the current component’s configurations
Examples¶
The following examples show how to use this component in a Builder script:
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(<x>, <y>, <z>)
barometer.rotate(<rx>, <ry>, <rz>)
robot.append(barometer)
# define one or several communication interface, like 'socket'
barometer.add_interface(<interface>)
env = Environment('empty')
