A few words about this case study
The municipality of Niederweningen runs a public swimming pool. The main swimming pool has a length of 50 meters and 4 lanes.
Next to the main pool is a smaller pool for kids with a huge water slide. Those two main pools are connected via water pipes,
so that the same water body is circulating through the separated pools.
This pool is opened from Mai to September. The water temperature varies according to the weather. It can be as cold as 15 degrees and reach up to 25 degrees Celsius on a sunny week. The municipality of Niederweningen publishes the water temperature readings on their web site. This task is done manually and consists of the following steps:
1. The lifeguard manually measures the water temperature using a thermometer.
2. Subsequently the lifeguard writes the reading onto the chalk board at to pool entrance and
3. communicates the reading to the city hall by telephone.
4. The person in the city hall updates the HTML page with the newly measured value.
This approach works so far. However there are some drawbacks. It is work intensive as different actors have to work hand in glove. The person in charge of updating the internet site also needs to be available on weekends and holidays - the time when most guests will consult the municipality webpage in order to make an informed decision on whether to go to the pool. The current process is error prone as the water temperature value is processed manually - a task which is also quite boring.
The above described weak points can be eliminated by using TMOR. The following benefits can be achieved:
A) Valuable man power can be freed for more rewarding tasks
B) Next to water temperature, additional values of interest can be published - such as the air temperature (this with little effort)
C) The values can be measured in short time intervals - all data captured is stored in data base
D) Data base information can be used for extensive data analysis - It provides the essential foundation for business intelligence
E) Out of the box presentation abilities provide more attractive/meaningful data presentation for the pool visitor than the current one number display
TMOR's benefits do not come for free. The pool needs to be 'teched up' with a TMOR base station and eventually one or two bricks. An initial effort is needed to locate the ideal place for data collection - where will the water temperature be measured. Next to that, the TMOR base stations needs to be integrated into the pool wifi. And last but not least, the web server hosting the Niederweningen web page needs to provide an ftp access to TMOR, so that the values can be published on the internet.
