NPK SOIL FERTILITY Test Sensor

[@Vietnamcamping89]

Hey bro, do you have this product on shopee or lazada. many thanks

[@nikhilbhawar2002]

I want a report on this project

[@YosepArohman-xo1pp]

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

[@marcelotreviovelzquez6721]

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.

[@kskaditya5905]

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

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.)

[@omerkarabs8764]

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

[@ronaldmorrison2765]

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,

Hi sir, when i run the program, it only returns the nitrogen value, the other ones doesn't show on the serial monitor

[@nurhafizhawahyuhutomi3870]

I am using a sensor from CWT products but it only reads nitrogen, can someone help me?

[@kasek4164]

Can this work in water column of an aquarium to monitor and can I use an esp32?

[@Prashant-wj9jk]

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

[@explorerofeverything1806]

Amazing use Full for agriculture

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]

Did you fix it ? I have same problem

[@IrrigationSystem-s9n]

I also have the same problem

[@kskaditya5905]

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

[@swiffstream1723]

Where can I buy the max13487 rs485 board

[@SLSU-MCCCISA]

I bought the MAX13487, it still did not work. I always get 255 value.

[@kskaditya5905]

Did the issue get resolved ?

[@harshadhulipalla535]

Change the band to 4800​@@kskaditya5905

[@ManuellaDiffoTahboh-so8pd]

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

[@Sanju-gm5td]

Hi, did you find a solution yet?

[@swathiammu7462]

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

[@kskaditya5905]

It is available in nsk electronics website

[@TechClover1]

hi sir can you help me with power connections npk sensor and max485

[@ranniesumacot4576]

So MAX485 Modbus module will not work for this?

[@ronaldmorrison2765]

Sometimes it will but not reliably. Stick with the 13487/3485 if you want it to work every time.

[@suryab9777]

How much sensor cost

[@damianeitorguitar]

where i can find the datasheet for this sensor?

[@scienceraven1200]

how accurate is it and how often are there errors?

[@kskaditya5905]

Accuracy should be around 60 to 70 %

[@harshadhulipalla535]

I am getting various readings in the output the values are not stopping can help me​@@kskaditya5905

[@amithn5106]

Hi sir where can buy this sensor or can I rent it sir

[@akshaybokde6548]

What is cost of npk sensor?

[@paulhunt9533]

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

[@Roxill_19]

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

[@ஆடுகளம்-த1ல]

Good sir

[@jogarao6858]

Sir ,,can u sell to me,,
