Its already some time ago that I wrote my previous post in this series (Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 6)). In the meantime I did a lot of tests using the solar pannel and different types of batteries and discharge schedules monitored by a bitscope/Raspberry Pi combination ( http://www.element14.com/community/roadTestReviews/1986 ).   Now its time to wrap up and mount everything together in a neat package which can be placed in the backyard. In order to ...
Now we have a running 1-Wire Weather Station on the SPARK Core, as described in Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 5), we now come to the next step, as the station needs to be powered outside. We need to put the weather station somewhere in the backyard, where no external power is available. Commercial wireless weather stations mainly use a low power 433 or 868 link which transmits weather data once per minute or less and runs for months, if not years on a pair of ...
In my previous blog posts I mainly focused on the IoT aspects of the project. In Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 2) I showed a scan of the 1-Wire bus, which showed the devices in the 1-Wire Weather Station. In the last one Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 4) I showed how two extra 1-Wire temperature sensors ar read and published in the cloud. In Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 1) I very briefl ...
In my previous post Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 3) the weather station transformed more and more into an  internet-of-things device. But we are still not satisfied with this local webserver approach were currently all kinds of fancy dashboards and data visualization  systems are available. Spark.io promised us an data visualization tool for Q4 2014, but unfortunately this is delayed to Q2 2015 (https://www.spark.io/features#dataviz). Therefore I s ...
In Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 1) I described the motivation of the project. In Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 2) the first steps of programming the SPARK Core and interfacing it to the 1-Wire bus are described. I showed how the bus was scanned, and temperature values measured, but output was only sent to the serial USB port. Not really an The Internet of Things approach. I will now first look at the possibilities to pres ...
In Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 1) I described the motivation of the project. This part will focus on the first steps of programming the SPARK Core and interfacing it to the 1-Wire bus. I don't repeat the information which can be found on the spark.io website and user forum, just a description of what I did to get the project going and some opinions about the spark.io system.   Although the SPARK language is almost similar to Arduino, it can not be pr ...
Almost 15 years ago I worked on an Internet of Things project. Yes, I know, the IoT concept wasn't used by then, but the technology was there. The device I used was the TINI (Tiny INternet Interface), a product of Dallas Semiconductor, which company later was acquired by Maxim. The "board" was a 68-pin SIMM that is approximately 103 mm wide, 32 mm tall running Java. There was a small unix like operating system and even a web server. Believe me or not, I still have a door lock with access contr ...
