Is there anyone who knows if I can use it directly connected to the Netduino, or if I have to build some control circuit? Documentation at http://www.murata.co...og/pdf/s21e.pdf, the original Murata site, is of no use, or at least I think...
I tried to use the sample code I found at http://forums.netdui...h__1#entry17181 and http://forums.netdui...h__1#entry26933 thinking that it would be the same, or similar, but no way... :-(

Studying better the datasheet, it looks like the E710 doesn't work on voltage, but in wave frequency, or something like that. I'm absolutely not expert: how can (if possible) the Netduino read such a signal? Thanks again Andrea
