[Visit Netafim's website at www.netafim.com Go directly to the sensor : http://www.netafim.com/cgi-bin/Serve/pages/English/1.5.7.7 Bruce] Luis Samoiloff <Luis@netafim.com> wrote After reading the Arie Nadler exposition about Netafim Soil Moisture Sensor, I want to clarify the present status of this sensor as to my knowledge (without taking part in the finantial dispute between Arie and the developers group, if it exists). The sensor works, not only as an off/on signal for irrigation of a single valve but also as a indicator of the soil moisture status. There is a station for soil moisture data collector that collects data from up to three moisture sensors, this data collector is brought to PC for reading of the collected data. Software for filing and graphic printouts included. The automatic data collector collects data from up to 960 readings. Reads automatically every 1 min. to 100 hours, adjustable. 9V battery( 1 year operation). For those lucky researchers having TDR (15000$)equipment, I strongly advise them to continue the good work with this kind of sensors (are all the problems with this technology and the output interpretation resolved?). To farmers, irrigation experts etc, I recommend to invest a few hundred dollars (maybe $200? for the automatic three station sensors) in order to have more information in the soil moisture status.
