Current Flesk Level

Well, the rain has finally returned so lets hope that this graph gets to see a bit of action over the next few months, Daithí 3-12-07

To check the lastest level, ring  +353-86-3029881 and count the number of beeps.  eg, 7 beeps means that the level is between 70cm and 80cm. If you hear a pitter-patter in the backgroung, that is the sound of rain bouncing off the box housing the system!






70cm is just runnable, tough on gear, no big holes on the drops but
falling over in the wrong place could well require a trip to the hospital
100cm is medium, holes have appeared, swims are nasty
130cm and above is high, not for the faint hearted

How often is this graph updated?

The unit at the river measures the level every 15 minutes and stores the data locally. To get the latest reading, ring the phone
and count the number of beeps. Once a day just after 09:00 (summer time), the unit sends an sms message containing all of
the data for the previous 24 hours. It takes about another 15min for the data to be converted to an email, delivered to the server
and processed to generate the graphs. The online graphs are therefore updated only once a day at about 09:20. This keeps the
phone bill down to just over E40 a year.

How does it work?

I have put an explanation of the system, pictures and a schematic here.

Phone access

Although the graph is only updated once a day, up to date information can be obtained by ringing the system. The will give a reading obtained
within the last 15 minutes. To check the lastest level, ring  +353-86-3029881 and count the number of beeps.  eg, 7 beeps means that the level
is between 70cm and 80cm. If you hear a pitter-patter in the backgroung, that is the sound of rain bouncing off the box housing the system!

Email alerts

There is also an email alert facility. To subscribe send an email to flesk-request@freelists.org  with the word subscribe in the subject line.
If the level is above 1m, a one line email is sent out. This will happen once a day at about 9.00am and only if the Flesk is running above 1m.
