Very similar to this post, I have now set up two sensors to share their data with the world on Thingspeak. The difference is that it will be powered by a wall adapter to have data over a bigger time period. I did this because some civil engineering architecture students are doing an exercise next week for which they could use this data. But it’s also useful for myself because I still need to learn how to receive data from Thingspeak (over a bigger time period) and do something useful with it.

Transferring data from 2 sensors to Thingspeak
Building a Twitter Reader
This Twitter Reader is capable of displaying recent Tweets. It was the latest exercise in the book “Building Wireless Sensor Networks” that I didn’t do yet.

A connection between a sensor and ThingSpeak
ThingSpeak is an open source “Internet of Things” application and API to store and retrieve data from things using HTTP over the Internet or via a Local Area Network. With ThingSpeak, you can create sensor logging applications, location tracking applications, and a social network of things with status updates. (source)
Building a Romantic Lighting Sensor (video)
This video shows my “Romantic Lighting Sensor”. It let’s me know when my place is lit romancally. It is one of Robert Faludi’s example projects in his book “Building Wireless Sensor Networks”. The video above shows the basic version where the yellow light starts to shine if the lighting is good enough. The Red flickering light indicates if the XBee’s are communicating with each other.

Building a doorbell (video)
“The Doorbell” is one of the first exercises in Robert Faludi’s book “Building Wireless Sensor Networks”. An XBee is attached to an Arduino to make wireless communication between the two boards possible. When the button is pushed on the button-board, it sends a signal (“D”) to the other board. This board, the bell-board, receives this signal and responds with the sound of a buzzer. Read on… →
Soldering Fun
Today I soldered an “XBee socket” and some “Break Away Headers” to my Sparkfun Breakout Board. This board makes it possible to plug an XBee on a Breadboard. It’s not the easiest way to accomplish this, but certainly the cheapest. I advise everyone to read through the warnings on the Sparkfun website and pay attention on how much solder runs down into the holes!
The soldering solved my XBee problems mainly because I made the false assumption that unsoldered connections are also good…
