This must be the most unusual use of 1-wire to date. I think the sprinklers have a lag, (it would make sense, a real fire doesn't have fast transients) so the sensing might be fine.
What will you do with the information. Also, the description from the link mentions fire performers, fireworks, etc. The sprinkler must really have put a damper on the performance.

There was a slight problem on opening night where the fire sprinkler over center stage went off. Too much heat generated from one of the fire effects. I was thinking of trying to use some DS18S20 sensors to monitor the temperature above the various fire effects. The sensors would be mounted to the ceiling above the various fire sources. The DS18S20 looks to have a range that'll support our needs, -55°C to +125°C. Since the sprinklers trigger at around +82°C that should work fine. But I'm concerned about being able to monitor temperature changes fast enough to provide accurate monitoring. The two aspects of that are how fast / often can I realistically expect to read the temperatures on a string of 5 to 7 sensors and how fast do the sensors themselves react to changes in temperature. Any thoughts or comments would be appreciated. Thanks! - Peter P.S. For anyone interested who would be using fire to tell the story of Romeo & Juliet, see http://thecrucible.org/ballet/index.html for details. ------------------------------------------------------------------------- Take Surveys.
