High precision soil moisture sensor

The soil moisture sensor is a device which detects the amount of water present in the soil, a necessary information to determine the uniformity of the growth conditions of the plants and for the following corrective actions. Understanding the real state of soil moisture leads to a careful management of water resources and treatments to preserve the health of the plants. The water in the soil is an electrical conductor and according to its concentration is possible to obtain an indication of humidity in the soil as much more accurate as more complex is the method of measurement. The sensor uses a frequency measurement (FDR), is precise and temperature compensated to achieve an accuracy up to 3%.

Electrical standard output is 0 ÷ 1.5 Vdc for a range up to 100 % VWC.
