Didier,

Normally you use a second sensor. You might be able to use the same sensor, but you need to make sure they won't interfere with each other's supply voltage. This can be complicated. For a start, see this: http://www.megamanual.com/v22manual/sharesen.htm

thank you for the fast answer, i think i'll go with two sensors, it's more easy and secure
