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.

This project is work in progress. It’s a proof of concept of  Internet of Things. It is demonstrated live quite often so we decided to put it up here. Your always welcome to suggest improvements and possible customers of the applications.

Above are screenshots of the splaschscreen, the login screen that unlocks the application, the mainscreen showing the status of the locks as well as the operator buttons to lock/unlock them and the settings screen.

Walktrough of the iPhone application.  ( Login with personal code to app. Open/Lock operations. Communication settings for a lock. Verification of lock settings. )


Test of iPhone app with Assa 3000 remote controlled lock. ( The Assa 3000 lock is operated by hand, and not really motorized. It can only disconnect the outside handle from operation = locked. )

We have some fake locks up and running on this server so you can test the app. (The scripts are 10 lines of php code, so don’t expect anything fancy.)
