Overview

Measuring the N(nitrogen), P(phosphorus), and K(potassium) contents of the soil is necessary to determine how much additional nutrient content needs to be added to the soil in order to improve crop fertility. Soil fertility was measured by NPK sensor. The main components of soil fertilizers are nitrogen, phosphorus and potassium. Knowledge of soil nutrient concentrations can help us understand nutrient deficiency or abundance in the soil used to support plant production.

Soil nutrient content can be measured in a variety of ways, such as using optical sensors or using spectrometers. But the spectral analysis method is not convenient, the disadvantage is that the accuracy of the data is only 60-70%. Although spectral analysis methods are compared with traditional wet chemical methods, the accuracy of the product has not been fully resolved due to the lack of data in this area.

JXCT Soil NPK Sensor

Therefore, here we will use JXCT soil nitrogen, phosphorus and potassium sensor to detect nitrogen, phosphorus and potassium in soil. JXCT Soil NPK Sensor is a low cost, fast response, high precision and portable sensor that works with Modbus RS485. Compared with traditional detection methods, the sensor has the advantage of very fast measurement speed and very accurate data. All you need to do is insert the detector into the soil and get a reading with the Arduino. So, let’s take a closer look at the interface between the soil NPK sensor and Arduino.

Soil nitrogen, phosphorus and potassium sensor is suitable for the detection of nitrogen, phosphorus and potassium content in soil. It helps to determine soil fertility and thus facilitates a systematic assessment of soil condition. Sensors can be buried in soil for long periods of time. It has a high quality probe, rust resistance, electrolytic resistance, salt and alkali corrosion resistance, to ensure the long-term operation of the probe components. Therefore, it is suitable for all kinds of soil. It is suitable for the detection of alkaline soil, acid soil, matrix soil, seedling bed soil and coconut bran soil.

The sensor does not require any chemicals. It has the characteristics of high measuring accuracy, fast response speed and good interchangeability. It can be used with any single chip microcomputer. You can’t use the sensor directly with the microcontroller because it has a Modbus communication port. Therefore, you need any Modbus module such as RS485/MAX485 and connect the sensor to the microcontroller. Sensors operate at 9-24V with very low power consumption. When it comes to sensor accuracy, it’s up to 2 percent. The resolution of nitrogen, phosphorus and potassium can reach 1mg/kg (mg/l).
