NPK sensor soil nutrients detection sensors modbus rs485

The soil NPK sensor and soil NPK detector are suitable for detecting the content of nitrogen, phosphorus and potassium in the soil. By detecting the content of nitrogen, phosphorus and potassium in the soil, the fertility of the soil can be judged, which is convenient for customers to systematically evaluate the soil condition. The soil NPK sensor is suitable for all kinds of soil, can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting and completely waterproof.

Soil nitrogen,phosphorus and potassium sensor RS485 measuring instrument soil nutrient fertility tester features:

(1) Convenient measurement: soil nitrogen, phosphorus and potassium detection is no longer limited to industry professionals, and the soil NPK sensor can be inserted into the soil to measure the nitrogen, phosphorus and potassium content in the soil;

(2) Low measurement cost: Compared with traditional laboratory measurement, the soil NPK sensor has low threshold, low cost, few steps, no reagents, and unlimited number of tests;

(3) High precision: The soil NPK sensor has high precision, fast measurement speed, and quick on-site inspection. It is easy to carry and insert into the soil to get the number, which shortens the time and cost.

Soil NPK sensor details.

The Soil NPK Sensor is suitable for detecting the levels of nitrogen, phosphorus and potassium in the soil. It helps to determine the fertility of the soil and thus facilitates a systematic assessment of soil conditions.

The sensor can be buried in the soil for long periods of time. It has a high quality probe, rust resistance, electrolytic resistance, and salt and alkali resistance to ensure the long-term operation of the probe section. Therefore, it is suitable for all kinds of soils. It is suitable for detecting alkaline soil, acidic soil, substrate soil, seedbed soil and coconut bran soil.

It can be used with any microcontroller due to its high measurement accuracy, fast response time and interchangeability. Since the sensor has a Modbus communication port, it is necessary to require any Modbus module (e.g. RS485) and connect the sensor to the microcontroller. The sensor runs on 12-24V with very low power consumption. When it comes to the accuracy of the sensor, it is up to 2% . Nitrogen, phosphorus and potassium are measured with a resolution of up to 1mg/kg (mg/l).
