It should work somehow, I have two of them digged, getting something between 0.30 (dry) and 1.29 (wet) in the current field.
BUT: I had many problem getting them to work and still have to reset them every few weeks as they "hang up" somehow! The order of connecting them seemed to be relevant, connecting GND (both 1w and supply consurrently) at last worked for me.. And there was a big issue when using any two sensors digged with GND and flapping values, I had to add an isolation-transformer between board and gypsum-sensor, see here: http://www.cocoontech.com/forums/index.php?showtopic=12330 You should calibrate them yourself *after* adding the transformer (if needed)..
