get_sensor_value()

Synchronously get current value of a sensor.

Reference

Arguments

Return

Curent value of the sensor or group of sensors (see the examples below).

Exceptions

• RayaSensorsInvalidPath

See the complete sensors exceptions.

Usage example

Reading temperature

Works with any continuous sensor

...
temp = self.sensors.get_sensor_value('/temperature')
self.log.info(f'Temperature = {temp}C')
self.log.info(f'Data type = {type(temp)}')
...

Output:

Temperature = 19.4C
Data type = <class 'float'>

Reading center line sensor

Works with any boolean sensor

...
center_line = self.sensors.get_sensor_value('/line_sensor/1')
self.log.info(f'Line state = {center_line}')
self.log.info(f'Data type = {type(center_line)}')
...

Output:

Line state = False
Data type = <class 'bool'>

Reading IMU Acceleration

Works with any group of sensors, or any 'incomplete' path

...
imu_acc = self.sensors.get_sensor_value('/imu/lin_acc')
self.log.info(f'IMU Acceleration = {imu_acc}')
self.log.info(f'Data type = {type(imu_acc)}')
...

Output:

IMU Acceleration = {
    'x' : 0.0024,
    'y' : 0.0438,
    'z' : 0.9763,
}
Data type = <class 'dict'>

Reading all the Sonars

Works with any group of sensors, or any 'incomplete' path

...
sonars = self.sensors.get_sensor_value('/sonar')
self.log.info(f'Sonars = {sonars}')
self.log.info(f'Data type = {type(sonars)}')
...

Output:

Sonars = {
    '1': 0.25,
    '2': 0.12,
    '3': 0.54,
    ...
}
Data type = <class 'dict'>
