Introduction: For those unaware of the event, CeBIT is held annually on the Hanover fairground. For an idea of scale, the exhibition area roughly covers 450.000m2 and the five day event attracted over 300.000 visitors this year. For those of you who know the IP EXPO in London, imagine 15+ halls like it and multiply […]

Introduction: This is the first of a series of posts to describe my second Arduino automated greenhouse. It’s simply too big a project to cover everything in one post so I’ve decided to split it into a few smaller posts. In this first part I’m going to quickly describe my water, power and network setup.

1. Introduction: I made a water level sensor a little while a go to measure the water level in my underground rainwater harvesting tank. Thanks to the Jubilee I found time to finally setup the first part of my Arduino/Xbee wireless sensor network and the first sensor node was also meant to read from this
1. Introduction I developed this WSN for a coursework on my MSc and I’m hoping others will find this useful or at least interesting 🙂 I’ve just installed the first parts of this WSN back home to collect sensor data from various outbuildings and it will be part of my new Arduino controlled greenhouse project.
1. Introduction: I went on free sample spree a little while ago and then got myself a few “younametheDIYunfriendlypackage”-to-DIP adapters off ebay (more details on the adapters are in one of my previous posts (DIP adapters to convert less DIY friendly packages (SOP, SOIC, TSSOP, MSOP, SSOP, SOT, LCC, LGA)). This is the first little
Introduction: I’ve always had a thing for 3D pictures and movies hence my recent acquisition of a HTC EVO 3D. It’s the US Sprint version hence only works on Wifi in this coutry due to the lack of a LTE network. But since I simply want to use it as a 3D camera it was

Introduction: The friendly postman left me a “you weren’t home” card yesterday so I got curious since I didn’t expect any deliveries. Farnell had given me a delivery slot for next week (28/05/2012 onwards) but a quick look into my profile confirmed that they had already sent it 🙂 Followed by the usual 24hr wait

Introduction: Texas instruments were kind enough to provide me with samples of their tmp175 digital temperature sensor. They don’t come in the most DIY friendly package hence I had to make a breakout board before I could get the Arduino to talk to one of them. The breakout board: I’m sure they are available somewhere
Introduction: I bought a few tmp102 sensors on matching breakout boards from SparkFun to take measurements around the greenhouse. Apart from the fact that this sensor is tiny, very energy efficient and responsive I mainly decided to go for these instead of thermistors because they are digital (no need for endless conversions) and since they
