The JXBS-3001-NPK-RS soil sensor measures three main nutrients. It tracks nitrogen, phosphorus, and potassium levels in the dirt. Farmers use these facts to pick the right fertilizer for their crops. This device uses a high-quality probe to find nutrient levels. It works well for precision agriculture and greenhouse monitoring. The sensor sends data through an RS485 interface. This connection uses the Modbus RTU protocol for simple integration with other tools. You can connect it to a PLC or a data logger. It runs on a wide power range from 5V to 30V DC. You can use it with a 12V or 24V supply.

The stainless steel probes resist salt and acid in the soil. Does the sensor resist corrosion? Yes, the stainless steel needles prevent rust from moisture. The IP68 casing keeps water away from the internal electronics. This build lasts a long time in the field. The measurement range goes up to 1999 mg/kg for each nutrient. It reacts in under one second. Accuracy stays within 2 percent for most tests. Many agricultural projects in Bangladesh require precise nutrient data. You can find the JXBS-3001-NPK-RS price in Bangladesh at local electronics shops. Buying an NPK sensor price in BD helps small farms save money on fertilizer.

Local shops in Dhaka sell these parts for students and engineers. The soil testing equipment Dhaka market is growing fast. You can use these tools for rice fields or mango orchards. The sensor needs very little power to run. It stays cool during long hours of operation. The cables are thick and strong. They resist damage from sun and rain. The Modbus RTU soil sensor setup is simple. You just need to set the correct address. Then the data flows to your screen. This sensor helps users manage smart farming sensors Bangladesh projects.

Frequently Asked Questions

Can I use this with an Arduino?
Yes, you need an RS485 to TTL converter to read the signal.

Where can I get the JXBS-3001-NPK-RS datasheet?
Most local sellers provide the manual in digital form after you purchase the item.

Is it better than cheap analog sensors?
Yes, the RS485 signal stays clear over long distances and resists interference.

How deep should I bury the probe?
You should bury the needles completely in the ground for the best results.

Does it need calibration?
The factory calibrates every unit before shipping to buyers.
