BMP085 Barometric Pressure Sensor Breakout Boards arrived!

17 February 2010 Shop

You may know that I played around a bit with the BMP085 barometric pressure sensor. Now I am proud to announce that the BMP085 barometric pressure sensor is available as breakout board in the Interactive Matter Shop.

The BMP085 Breakout Board is a limited offer. I just got some at hand and supplies last as long [...]

Palo Altona – Hamburg Tinker Drinkup

14 January 2010 Tinkering

Die deutsche Version gibt es nach dem Klick (und dann weiter unten).
This time it is all non-technical (technically not – but that starts to get complicated). To further encourage tinkering in Hamburg, Alex and I have established a regularly tinker drinkup every Thursday (nearly) at Saal II.

Currently it is a very cosy drinkup, just a [...]

Filtering Sensor Data with a Kalman Filter

18 December 2009 Tinkering

Some days ago I wrote about noise with a LIS302DL accelerometer. There is obviously something wrong with my hardware. But before I get a new version out I need to implement some software filtering.

After some unsuccessful results with low pass filters I choose the Kalman Filter. The Kalman Filter involves an awful lot of complicated [...]

Arduino & Barometric Pressure Sensor BMP085

5 December 2009 Sensors

In lack of any new projects (which are currently all in an very intermediate state) Interactive Matter presents yet another ‘how to connect a cool I2C sensor to Arduino’ post.
This time it is all about pressure. The BMP085 pressure sensor combines a absolute barometric pressure sensor (aka barometer) with an temperature sensor. It is build [...]

Arduino & AD7746

18 July 2009 Sensors

In my ongoing series about cool sensors Interactive Matter presents the AD7746 capacity sensor:

What is a capacity sensor good for? You can of course make a device to identify small capacitance (up to 4pF) but that’s boring. Much more interesting is how it reacts to touching.
Read on how to connect it to the Arduino and [...]

Arduino & LIS302DL

13 February 2009 Sensors

Ages ago I bought an LIS302DL from Sparkfun. One of the old (little bit) messed up ones, but still 3 axis accelerometer with I2C output. No external parts. No pain. Fine!

Before I go in any further investigation. I need to get it up & running with my arduino (actually an boarduino – but who cares?). [...]

Tinkering with ADJD-S371-Q999

17 August 2008 Sensors

The initial idea of “How was your day, darling” was to record the colors for a day. You know a morning is golden, evening is reddish, thunderstorm is greenish and so on. Measuring this with a simple RGB LED is a brave approach – but hard and cumbersome. So I ordered an ADJD-S371-Q999 color sensor [...]
