I noticed there has recently been a page added on Sensera's website dedicated to the Towakon water leaking sensor, including a new video and PDF presentation of the product: http://sensera.com/towakon-water-conservation-sensor/
I thought Towakon was dead and buried but perhaps not. It will be interesting to see if they find a partner to commercialise or license the technology. Perhaps some news on this front shortly?
Cheers
