The TDR-315L is a true waveform digitizing Time Domain Reflectometer that derives soil permittivity and water content from the propagation time of an electromagnetic impulse conveyed along its waveguide. Like many of its expensive predecessors (conventional TDR mainframes) it contains an ultra-fast rise time step function generator, a waveform digitizer (200 GSPS) and a picosecond-resolution time base (5ps). Unlike these predecessors it eliminates the bandwidth-constraining coax cable, the bulky console, and 90-97% of the cost. Because it is a true time domain device its readings are not derived from current and voltage magnitudes and relationships and hence are not impacted by soil electrical conductivity and compaction. Its high immunity to EC allows credible application in non-saturated soils wetted with sea water. It uses the standard SDI-12 interface and is compatible with all data recorders that are version 1.3 compliant. Functions: Volumetric Water Content (0 to 100% with 0.1% resolution) Permittivity (1 to 80 with 0.1 unit resolution) Soil Electrical Conductivity a.k.a. Bulk EC (0 to 5000 μS/cm -resolution depends on reading range) Soil Temperature (-40 to +60 degrees C with 0.1 degree resolution) Pore Water Electrical Conductivity (0 to 55000 μS/cm)

This is an easy to use digital soil moisture sensor. Just insert the sensor in the soil and it can can measure moisture or water level content in it. It gives a digital output of 5V when moisture level is high and 0V when the moisture level is low in the soil.The sensor includes a potentiometer to set the desired moisture threshold. When the sensor measures more moisture than the set threshold, the digital output goes high and an LED indicates the output. When the moisture in the soil is less thatn the set threshold, the output remains low. The digital output can be connected to a micro controller to sense the moisture level. The sensor also outputs an analog output which can be connected to the ADC of a micro controller to get the exact moisture level in the soild.
