This is our El Wifi TH Sensor

It is located in our livingroom. You can see the latest readings (samples) of the sensor near-realtime on this webpage. To collect these samples, we wrote a program in C#, called Sensor Monitor. It runs (optionally in the tray) on a Windows computer with at least .NET 4 client profile. The software of El-Wifi does not have to be installed for it to run.

Sensor Monitor

Sensor Monitor listens to UDP broadcasts sent by the sensor. When the sensor is in sleepmode, these broadcasts occur every 15 minutes. There are up to 255 samples (ie readings with temp / humidity) in one broadcast.

When the sensor exceeds this maximum, the samples above 255 will be remembered by the sensor, but not broadcasted. To read these higher samples, a program has to send a (confirmation) response to the sensor. Sensor Monitor therefore sends a response after 200 samples, making sure the buffer never gets above 255 samples. You can not retrieve samples with the El-Wifi software after a confirmation response, because the buffer is cleared by this. After the broadcasts stop, Sensor Monitor will upload the collected data to this website. There it will be saved as XML and be rendered as html when you visit this webpage.

Free download

You are free to use Sensor Monitor with your own sensor. Sensor Monitor will show you a button to this website with the MAC address of your sensor in the URL (wait for this after the first samples are collected, then this button will be available). Press this button and you will see your sensor on the web.

There are up to 10,000 samples stored for each sensor, but that's just a software limitation we have built in. Samples are stored as XML on the website, which you may also request directly to process further. If you want to do this, let us know.

Source code

If you're interested in part of the sourcecode, you can download it here. Please don't use the code for commercial projects.
