SINOSO ISM intelligent soil wall detector is a soil water content detector based on the advanced frequency domain reflection (FDR) measurement principle. It can dynamically detect soil water content and temperature at different depths at the same time, with fast measurement speed and high accuracy. The ISM intelligent soil wall indicator uses a high-performance micropower processor, built-in lithium battery and wireless communication module, and requires no external wiring. It is mainly suitable for soil moisture monitoring such as agricultural production and geological disaster.
