WaterScout SM 100 Soil Moisture Sensor Description：

Product Manual

The key is knowing both when and how much to water!

Maintaining a healthy soil moisture and water balance is essential for producing high quality plants. Under-watered plants suffer from nutrient deficiencies, stunting and wilting. Conversely, over-watered plants are more susceptible to disease pressure and less tolerant of dry conditions later on in their life cycle. Extreme over-watering will suffocate the plant and lead to root death.

Measures Volumetric Water Content (VWC) of soil

Capacitance-type sensor responds immediately to changes in soil moisture content for better irrigation decisions

Calibrated for mineral soils or soilless media

Installs easily into 3/4 in (1.9 cm) hole

Install permanently or use to take spot measurements

Can be read with the FieldScout® Soil Sensor Reader (Item 6466) or WatchDog® 2000 and 1000 Series Stations

Connect up to 8 sensors to one station Not compatible with 400/200 loggers.
