| Abstract: | Sensor methods have marly advantages in soil moisture detection compare with other ways. A soil moisture detection circuit is designed and the principle and constitute of switchcireuit is expatiated. The experiment indicates that the resolution of testing water content in soil by this circuit is 0.1% ,the difference with traditional weighing method is less than 5 %. The main characters are high precision, testing fast, display visual, simple to use, cheap and easy to operate. |
