Soil NPK Sensor 5V RS485 JXCT

The soil NPK sensor is appropriate for measuring the levels of nitrogen, phosphorous, and potassium in the soil and determining the soil’s fertility by detecting the levels of N, P, and K in the soil. The soil NPK sensor’s stainless-steel probe can be inserted into the soil for an extended period and is durable against prolonged electrolysis, salt, and alkali corrosion. The shell is sealed and fully watertight.
