### Description
Retrieve various properties and information about the connected sensor device, such as its family, features, commands, name, state, address, serial number, power status, sampling frequency, gain, data offset, and firmware/hardware versions.

### Usage
```python
print(sensor.sens_family)  # SensorFamily.LEBrainBit
print(sensor.features)  # [<SensorFeature.Signal: 0>, ...]
print(sensor.commands)  # [<SensorCommand.StartSignal: 0>,...]
print(sensor.parameters)
print(sensor.name)  # BrainBit
print(sensor.state)  # SensorState.StateInRange
print(sensor.address)  # AA:BB:CC:DD:EE:FF
print(sensor.serial_number)  # 123456
print(sensor.batt_power)  # 50
print(sensor.sampling_frequency)  # SensorSamplingFrequency.FrequencyHz250
print(sensor.gain)  # SensorGain.Gain6
print(sensor.data_offset)  # SensorDataOffset.DataOffset0
print(sensor.version)  # SensorVersion(FwMajor=50, FwMinor=0, FwPatch=0, HwMajor=1, HwMinor=0, HwPatch=0, ExtMajor=65)
```
```

### Receive Signal and Resistance Simultaneously

Source: https://pypi.org/project/pyneurosdk2

Use this callback to receive both signal and resistance data. Note that resistData may not arrive with every SignalResistReceived callback update.

```python
def on_signal_resist_data_received(sensor: Sensor, signal: list[SignalChannelsData], resist: list[ResistChannelsData]):
    print('Signal: {0}'.format(signal))
    print('Resist: {0}'.format(resist))

sensor.signalResistDataReceived = on_signal_resist_data_received
sensor.exec_command(SensorCommand.StartSignalAndResist)
...
sensor.signalResistDataReceived = None
sensor.exec_command(SensorCommand.StopSignalAndResist)
```

--------------------------------

### Receive Resistance Data

Source: https://pypi.org/project/pyneurosdk2

Subscribe to resistance data using a callback function. Ensure to stop the resistance stream and unsubscribe the callback when done.

```python
def on_resist_data_received(sensor, data: list[Headphones2ResistData]):
    print(data)

sensor.resistDataReceived = on_resist_data_received
sensor.exec_command(SensorCommand.StartResist)
...
sensor.exec_command(SensorCommand.StopResist)
sensor.resistDataReceived = None
```

--------------------------------

### Receive Signal Data

Source: https://pypi.org/project/pyneurosdk2

Subscribe to signal data using a callback function. Ensure to stop the signal and unsubscribe the callback when done.

```python
def on_signal_data_received(sensor, data: list[Headphones2SignalData]):
    print(data)

sensor.signalDataReceived = on_signal_data_received
sensor.exec_command(SensorCommand.StartSignal)
...
sensor.exec_command(SensorCommand.StopSignal)
sensor.signalDataReceived = None
```

--------------------------------

### Clean Up Sensor and Scanner Resources

Source: https://pypi.org/project/pyneurosdk2/1.0.9

Manually release resources held by the sensor and scanner objects when they are no longer needed. This is typically handled by the garbage collector, but explicit deletion can be necessary.

```python
del sensor
del scanner
```

--------------------------------

### Sensor Found Callback

Source: https://pypi.org/project/pyneurosdk2/1.0.9

Define and assign a callback function to the sensorsChanged attribute to be notified when sensors are found or lost.

```python
def sensorFound(scanner, sensors):
   for i in range(len(sensors)):
       print('Sensor %s' % sensors[i])

scanner.sensorsChanged = sensorFound
```

--------------------------------

### Stop Device Search

Source: https://pypi.org/project/pyneurosdk2/1.0.9

Terminate the device search process using the scanner.stop() method.

```python
scanner.stop()
```

--------------------------------

### Unsubscribe from Resistance Data Reception

Source: https://pypi.org/project/pyneurosdk2/1.0.9

Disable the callback for resistance data to stop receiving resistance values. Assign None to the resistDataReceived property.

```python
sensor.resistDataReceived = None
```

--------------------------------

### Unsubscribe from Signal Data Reception

Source: https://pypi.org/project/pyneurosdk2/1.0.9

Remove the callback for signal data reception to stop receiving updates. Set the corresponding property to None.

```python
sensor.signalDataReceived = None
```

--------------------------------

### Unsubscribe from Electrode State Changes

Source: https://pypi.org/project/pyneurosdk2/1.0.9

Disable notifications for electrode state changes by setting the electrodeStateChanged property to None.

```python
sensor.electrodeStateChanged = None
```

--------------------------------

### Disconnect from Device

Source: https://pypi.org/project/pyneurosdk2/1.0.9

Terminate the connection to the currently connected device using the sensor.disconnect() method.

```python
sensor.disconnect()
```
