Winter field trials – remote measurement and decision support system

Update: The Swedish newspaper ATL wrote about the measurement project (in Swedish).

The winter field trials are ending and we consider it a success. We have together with our partners placed a total of 74 wired and wireless sensors at five locations in the southern part of Sweden. The largest problem was the winter storm ”Emil” that cut the electricity to the GSM networks cell towers for about 5 hours one night disrupting the service in Norje, Blekinge. Once the GSM network was operating the system in that area was also back online.
You can order the product from (in Swedish).

Below is a typical temperature graph that can be viewed on the web, on a phone or on an iPad. The screenshot is from the web interface showing the measurements from one of the sensors placed in the above video, located at Svenstorps gods, Skåne.

Wireless decision system for farmers

The event Elmia Agriculture, Livestock & Technology took place 19-22 of October 2011. Liros Electronic in monter D01:39 showed wireless temperature sensors that could be observed on the web and in mobile apps on Android and iPhones.
Videocent helped bring Liros traditional wired and handheld temperature equipment up into the internet cloud and and then down into the hands of farmers and their mobile phones. Our work has so far included not only the making of web and apps, but we have also helped select ZigBee and GSM vendors, writing scripts for three internet cloud services and are on our way in discussions with a GSM operator.

 Below are two of the graphs. A dotted line means that the sensors are off-line, a filled line show actual measured values. These sensors are live when we experiment with the system and can therefore show very strange results from time to time.
