difference with soil moisture sensor v1.2

[javierb]

Hello everyone!
With no intention of offending anyone. I am newbie and i want to learn.
Could you tell me what are the main differences between SoilWatch 10 and the cheap Soil Moisture Sensor V1.2 apart from the good insulation of the soilwatch 10?

Hi,

This is a very good question 
Our sensor uses high frequency to measure the soil moisture. High-frequency help to reduce the salinity influence on moisture readings. I'm not sure what frequency this sensor uses but as far as I know it is well under 1MHz. The plates of the probe in our sensor are sandwiched between glass-reinforced epoxy laminate material. This protects them well from the environment. While these cheap sensor plates are covered with just paint. It is easy to scratch the paint while inserting the sensor into the soil. And the last difference I can think about now is the obvious weather-proofing.

Kind regards,
