Soil Sensor

SS204-04

四合一土壤养分传感器

产品亮点

● Four-parameter measurement combines moisture, temperature, EC and pH.
● Dielectric-constant measurement reflects volumetric soil-water content.
● Specially treated alloy electrodes resist external impact and corrosion.
● No reagents are required; the source states there is no limit on detection count.
● Low-power design supports wake, sample, upload and sleep workflows.
