Arduino and a humidity sensor HS15P

Informations

According to what I've read on the net, don't feed this with DC current. The electrolyse reaction will make the detector stop working after some time. AC will guarantee it to work long time. So guy suggest to stick with DC but leave to 0V all the time and feed it with low DC only when reading... that might be a compromise.
There is a schema to make a simple inverter with a 555 at the bottom of the documentation page on Akizukidenshi. I put some link to inverters schema here also .
As of today I still have not used those HS15P... but I will!
