Voltage output 3 pins soil moisture and temperature sensor 

The MS20 is a high precision and high sensitivity of soil moisture & temperature sensors. By measuring the dielectric constant of the soil, it shows stable real moisture content directly. The MS20 can measure the volume of soil moisture. The FDR soil moisture measurement method is in line with present international standards. Apply to the soil moisture monitoring, scientific experiment, water-saving irrigation, greenhouse vegetables, flowers, grass, fast measure, plant cultivation, greenhouse control, precision agriculture and the other measurement of water, weather or particulate matter content.

The sensor has following features:

1. Support customer soil type, the user can calibration

2. Contain moisture & temperature measure. High precision, quick response and good compatibility.

3. Seal with Fire-retardant Epoxy Resin, IP68 water proofing. Long term usage.

4. Special treatment of probe material can be against acid and alkali corrosion.

5. Widely used in many kinds of soil because of the imported advance tech which correct the effect of different salt content.

6. Multiple protection functions including Power supply, communication, analog output. High reliability.
