openHAB - Accelerometer Bricklet

Warning

The openHAB bindings are still in beta, but the development was stopped.

This is the description of the openHAB API bindings for the Accelerometer Bricklet. General information and technical specifications for the Accelerometer Bricklet are summarized in its hardware description.

An installation guide for the openHAB API bindings is part of their general description.

Thing

UID:
  • tinkerforge:brickletaccelerometer:[UID]
Required firmware version:
  • 2.0.0
Firmware update supported:
  • yes
Channels:
Actions:
Parameters:
  • Data Rate – Type: Choice, Default: 100Hz
  • The data rate of 0Hz to 1600Hz. Decreasing data rate or full scale range will also decrease the noise on the data.
  • Options: Off, 3Hz, 6Hz, 12Hz, 25Hz, 50Hz, 100Hz, 400Hz, 800Hz, 1600Hz

  • Full Scale Range – Type: Choice, Default: 4g
  • Full scale range of ±2gₙ up to ±16gₙ. Decreasing data rate or full scale range will also decrease the noise on the data.
  • Options: 2g, 4g, 6g, 8g, 16g

  • Filter Bandwidth – Type: Choice, Default: 200Hz
  • Filter bandwidth between 50Hz and 800Hz.
  • Options: 800Hz, 400Hz, 200Hz, 50Hz

  • Acceleration Update Interval – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295
  • Specifies the update interval for the acceleration in milliseconds. A value of 0 disables automatic updates.

Read only:
  • Yes
Unit:
  • Celsius
Range:
  • -103 Celsius to 152 Celsius (Step 1 Celsius)
Parameters:
  • Update Interval – Type: integer, Default: 1000, Unit: ms
  • Specifies the update interval in milliseconds. A value of 0 disables automatic updates.
LED

Enables/Disables the LED on the Bricklet.

Type:
  • Switch
UID:
  • tinkerforge:brickletaccelerometer:[UID]:BrickletAccelerometerLED
Read only:
  • No

Actions

Actions can be used in rules by creating an action object. All actions return a Map<String, Object>. Returned values can be accessed by name, sometimes the type deduction needs some hints, as shown below:

val actions = getActions("tinkerforge", "tinkerforge:brickletaccelerometer:[UID]")
val hwVersion = actions.brickletAccelerometerGetIdentity().get("hardwareVersion") as short[]
logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))

Basic Actions

brickletAccelerometerGetAcceleration()
Return Map:
  • x – Type: short, Unit: 1/1000 gₙ, Range: ?
  • y – Type: short, Unit: 1/1000 gₙ, Range: ?
  • z – Type: short, Unit: 1/1000 gₙ, Range: ?

Returns the acceleration in x, y and z direction. The values are given in gₙ/1000 (1gₙ = 9.80665m/s²). The range is configured with the thing configuration.

If you want to get the acceleration periodically, it is recommended to use the Acceleration X channel and set the period with the thing configuration.

brickletAccelerometerGetTemperature()
Return Map:
  • temperature – Type: short, Unit: 1 °C, Range: [-103 to 152]

Returns the temperature of the accelerometer.

brickletAccelerometerLEDOn()

Enables the LED on the Bricklet.

brickletAccelerometerLEDOff()

Disables the LED on the Bricklet.

brickletAccelerometerIsLEDOn()
Return Map:
  • on – Type: boolean, Default: false

Returns true if the LED is enabled, false otherwise.

Advanced Actions

brickletAccelerometerGetConfiguration()
