JXCT Soil npk transmitter
NPK Soil Transmitter
Your plants, like you, need food. To be healthier and more productive, plants need the “big three” essential nutrients nitrogen, phosphorus and potassium, also known as NPK. If the soil in your garden doesn’t have enough of these nutrients, plants won’t be able to develop to their full potential. Therefore, the current N, P and K levels of the soil must be measured to determine how much additional nutrient content must be added to improve crop fertility. With the NPK Soil Transmitter, you can quickly determine the levels of these nutrients in your soil.
What is NPK? Why is it so important?
The letters NPK stand for the three main nutrients that plants need to grow and thrive: nitrogen, phosphorus and potassium. Nitrogen is responsible for the growth and green color of plant leaves. Phosphorus helps plants develop strong roots, fruits and flowers. Potassium improves the overall health and hardiness of plants.
JXCT Soil NPK Transmitter
The JXCT Soil NPK Transmitter is a low cost, fast responding, fairly accurate portable sensor. It helps in real-time monitoring of NPK nutrient content in smart agricultural soils. Soil NPK transmitters detect nitrogen, phosphorus and potassium in soil (not water). It helps determine soil fertility, allowing for a more systematic assessment of soil condition.
The best part is that the sensor has an IP68 rating, which means it is protected from dust and moisture, allowing it to function normally for a long time.
For effective use at long distances, the sensor has an RS485 communication interface and supports the standard Modbus-RTU communication protocol. It should be noted that the sensor cannot be used directly with an Arduino. To communicate with the Arduino you need an RS-485 transceiver module that converts the UART serial stream to RS-485.
Instructions for use
Choose a suitable measurement location, avoid stones, make sure the steel probe does not touch any hard objects, and insert the sensor vertically into the soil. Alternatively, the sensor can be inserted horizontally into the pit, in which case pits larger than 20 cm in diameter are excavated vertically before being tightly backfilled.
