NPK sensor can be used to determine soil fertility by measuring Nitroger,Phosphorous & Potassium content of the soil and decide on the required fertilizers to use.
It has 3 pins Stainless Steel Probe which is IP68 rating protected against rust,salt,alkaline.
RS485 communication protocol is used to enable long distance data transmit.
RS485 -TTL converter is required to use with Arduino.
MAX485 converters available in market have some voltage level issues and will not work with NPK.
We need to use MAX13487 auto direction enabled converter for effective data transfer.

Very usefull video sir please create video on jxct leafwetness sensor I have problem on leafwetness sensor

@Srinivasjr04 Год назад

Hi very nice information, could have been more useful if provided the online source of the components used (as we see many vendors with huge difference in the price, getting confused which one is right one.)

Good sir

@YosepArohman-xo1pp 4 месяца назад

sorry, I want to ask. Is the sensor calibrated or does it have to be calibrated first? If it has to be calibrated first, how do you calibrate it? please answer

Hey, I'm pretty sure my sensor is fully functioning. I made a test of sending HEX code with coolterm and using the sensor in some soil. I got the npk, potassium and phosphorous hexadecimal outputs, but when I want to use the RS486 software you provided, there is an error called ERROR(367):0. Maybe you need to add the CSkin.dll archive you have inside the folder where you opened the rs485 software app.

What version of rs485 did u use. In video he used max 13487 version. For this there is no need to define re and de But for the one available in, market that is max485, it needs re and de to be defined

Good evening I made a small assembly with a 3-pin NPK sensor but it only returned me 255 255 255 for the n p and k values

Hi, did you find a solution yet?

@omerkarabs8764 4 месяца назад

Is it possible to view the received data wirelessly on a computer?

@ronaldmorrison2765 4 месяца назад

Of course. It takes a different microcontroller and lots different programming but it certainly can be done. I'm pretty sure it can be done with an ESP32. The Arduino Uno does not have WIFI and it may not have the processor power either,

What is cost of npk sensor?

@nj1204 11 месяцев назад

Hello, I have verified all connections between Arduino Uno, 485 and NPK sensor, also made sure NPK sensor's power wire is connect to 12V DC power source, the code also looks correct with the same address value as in the manual, but it still always gives 255 value for All N, P K values. Any suggestion how I could resolve it?

@Poorbumi10 9 месяцев назад

Did you fix it ? I have same problem

@user-xt6bp1ny5x 6 месяцев назад

I also have the same problem

@kskaditya5905 6 месяцев назад

The problem lies in 485 module. I only know that. But don't know the solution

@swathiammu7462 Год назад

where can we buy Max13487 convertor. can someone share the link

@kskaditya5905 6 месяцев назад

It is available in nsk electronics website

@paulhunt9533 Год назад

hi,Sir please proivide the 485 sensor confgration tool ????

@Roxill_19 5 месяцев назад

same, i can't find that configuration tool edit: link in the description, then download NPK code you will see a bunch of folder and you will there the configuration tool
