Basic Functions¶

new BrickletAmbientLightV2(uid, ipcon)¶

Parameters:	uid – Type: string ipcon – Type: IPConnection
Returns:	ambientLightV2 – Type: BrickletAmbientLightV2

Creates an object with the unique device ID uid:

var ambientLightV2 = new BrickletAmbientLightV2("YOUR_DEVICE_UID", ipcon);

This object can then be used after the IP Connection is connected.

BrickletAmbientLightV2.getIlluminance([returnCallback][, errorCallback])¶

Callback Parameters:	illuminance – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1]
Returns:	undefined

Returns the illuminance of the ambient light sensor. The measurement range goes up to about 100000lux, but above 64000lux the precision starts to drop.

Changed in version 2.0.2 (Plugin): An illuminance of 0lux indicates an error condition where the sensor cannot perform a reasonable measurement. This can happen with very dim or very bright light conditions. In bright light conditions this might indicate that the sensor is saturated and the configuration should be modified (setConfiguration()) to better match the light conditions.

If you want to get the illuminance periodically, it is recommended to use the CALLBACK_ILLUMINANCE callback and set the period with setIlluminanceCallbackPeriod().

Advanced Functions¶

BrickletAmbientLightV2.setConfiguration(illuminanceRange, integrationTime[, returnCallback][, errorCallback])¶

Parameters:	illuminanceRange – Type: int, Range: See constants, Default: 3 integrationTime – Type: int, Range: See constants, Default: 3
Callback Parameters:	undefined
Returns:	undefined

Sets the configuration. It is possible to configure an illuminance range between 0-600lux and 0-64000lux and an integration time between 50ms and 400ms.

New in version 2.0.2 (Plugin): The unlimited illuminance range allows to measure up to about 100000lux, but above 64000lux the precision starts to drop.

A smaller illuminance range increases the resolution of the data. A longer integration time will result in less noise on the data.

Changed in version 2.0.2 (Plugin): If the actual measure illuminance is out-of-range then the current illuminance range maximum +0.01lux is reported by getIlluminance() and the CALLBACK_ILLUMINANCE callback. For example, 800001 for the 0-8000lux range.

Changed in version 2.0.2 (Plugin): With a long integration time the sensor might be saturated before the measured value reaches the maximum of the selected illuminance range. In this case 0lux is reported by getIlluminance() and the CALLBACK_ILLUMINANCE callback.

If the measurement is out-of-range or the sensor is saturated then you should configure the next higher illuminance range. If the highest range is already in use, then start to reduce the integration time.

The following constants are available for this function:

For illuminance_range:

Callback Configuration Functions¶

BrickletAmbientLightV2.on(callback_id, function[, errorCallback])¶

Parameters:	callback_id – Type: int function – Type: function

keep being reached.

Callback Parameters:	debounce – Type: int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 100
Returns:	undefined

Returns the debounce period as set by setDebouncePeriod().

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with the on() function of the device object. The first parameter is the callback ID and the second parameter the callback function:

ambientLightV2.on(BrickletAmbientLightV2.CALLBACK_EXAMPLE,
    function (param) {
        console.log(param);
    }
);

The available constants with inherent number and type of parameters are described below.

BrickletAmbientLightV2.CALLBACK_ILLUMINANCE¶

Callback Parameters:	illuminance – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1]

This callback is triggered periodically with the period that is set by setIlluminanceCallbackPeriod(). The parameter is the illuminance of the ambient light sensor.

The CALLBACK_ILLUMINANCE callback is only triggered if the illuminance has changed since the last triggering.

BrickletAmbientLightV2.CALLBACK_ILLUMINANCE_REACHED¶

Callback Parameters:	illuminance – Type: int, Unit: 1/100 lx, Range: [0 to 232 - 1]

This callback is triggered when the threshold as set by setIlluminanceCallbackThreshold() is reached. The parameter is the illuminance of the ambient light sensor.

If the threshold keeps being reached, the callback is triggered periodically with the period as set by setDebouncePeriod().

Virtual Functions¶

Virtual functions don't communicate with the device itself, but operate only on the API bindings device object. They can be called without the corresponding IP Connection object being connected.

BrickletAmbientLightV2.getAPIVersion()¶

Returns:	apiVersion – Type: [int, ...], Length: 3 0: major – Type: int, Range: [0 to 255] 1: minor – Type: int, Range: [0 to 255] 2: revision – Type: int, Range: [0 to 255]

Returns the version of the API definition implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

BrickletAmbientLightV2.getResponseExpected(functionId[, errorCallback])¶

Parameters:	functionId – Type: int, Range: See constants
Returns:	responseExpected – Type: boolean

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by setResponseExpected(). For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For function_id:

• BrickletAmbientLightV2.FUNCTION_SET_ILLUMINANCE_CALLBACK_PERIOD = 2
• BrickletAmbientLightV2.FUNCTION_SET_ILLUMINANCE_CALLBACK_THRESHOLD = 4
• BrickletAmbientLightV2.FUNCTION_SET_DEBOUNCE_PERIOD = 6
• BrickletAmbientLightV2.FUNCTION_SET_CONFIGURATION = 8

BrickletAmbientLightV2.setResponseExpected(functionId, responseExpected[, errorCallback])¶

Parameters:	functionId – Type: int, Range: See constants responseExpected – Type: boolean
Returns:	undefined

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For function_id:

• BrickletAmbientLightV2.FUNCTION_SET_ILLUMINANCE_CALLBACK_PERIOD = 2
• BrickletAmbientLightV2.FUNCTION_SET_ILLUMINANCE_CALLBACK_THRESHOLD = 4
• BrickletAmbientLightV2.FUNCTION_SET_DEBOUNCE_PERIOD = 6
• BrickletAmbientLightV2.FUNCTION_SET_CONFIGURATION = 8

BrickletAmbientLightV2.setResponseExpectedAll(responseExpected)¶

Parameters:	responseExpected – Type: boolean
Returns:	undefined

Changes the response expected flag for all setter and callback configuration functions of this device at once.

Constants¶

BrickletAmbientLightV2.DEVICE_IDENTIFIER¶

This constant is used to identify a Ambient Light Bricklet 2.0.

The getIdentity() function and the IPConnection.CALLBACK_ENUMERATE callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.

BrickletAmbientLightV2.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a Ambient Light Bricklet 2.0.
