Greetings...I would like to ask maam/sir, if the sensor detect this example value: N: 40 mg/kg P: 90 mg/kg K: 100 mg/kg What is the threshold of Low, Medium Low, Medium High, High, and Very High? And I ask too let say Nitrogen is Low how many amount of nitrogen need? Is the soil need 120, 100, 80, 60, 40, 30 nitrogen and so on?
Repeated this process and had really inaccurate readings and the it seemed as tho it wasn’t interfacing with the pulse sensor and the readings were coming back 0 or 255, seems like there’s some bugs in the code we triple checked wiring, code, & overall cannot figure if it’s a back sensor of if there’s more to the problem....?
The npk that I bought didn't work so well. It always shows the 255 mg/kg. How will I work the sensor properly? I already use the 12 volts but it is still not functional
Can u tell me how u gave power supply and in circiut diagrams u mentioned connections for NRF24L01 but in picture u gave connections to NRF24L01 PA LNA .Can u briefly give pictures with whole setup
Can you expand this post? Use ESP 32 to report to the phone, measure the NPK if any type is missing, then open the valve to supply the missing type NPK. otherwise it's okay,
Hi, your video is very helpful for my project. And, I need these as well 5. Magnesium 6. Lime 7. Silicon 8. Copper 9. Zinc 10. Manganese 11. Boron 12. Cation Exchange Capacity Can you help me in finding these sensors? Thank you
which algorithm did you use?
Thanks you so much for this video.
informative video...
I have an Temperature Humidity PH and EC sensor combined how can I find the register values

hello po, may threshold na po ba kayo tungkol sa NPK?

Did you figure it out? I'm having the same issue stuck at 255.

I have one error showing
Multiple libraries found Wifi.h
Agr/pgmspace.h no director found
Which software you have used for circuit making and if it is fritzing from where you got npk sensor part?
also my question
Can u tell me how u gave power supply and in circiut diagrams u mentioned connections for NRF24L01 but in picture u gave connections to NRF24L01 PA LNA .Can u briefly give pictures with whole setup
Please respond fastly admin sir we have to project
Which cast around this project ?
I need to know why I get 3 rows of continuous FFFFFFFF and all parameters values as 255 mg/kg?
The system will suggest what plants should be plant ?
Can't we use 1 nrf24L01 wireless transceiver module
Can you expand this post? Use ESP 32 to report to the phone, measure the NPK if any type is missing, then open the valve to supply the missing type NPK. otherwise it's okay,
Which kind of that programming computer
IT was a very interesting Project. Just a question how do you read 2 NPK sensors on the Arduino Code. Do you have a sample of the code?
Are there similar sensors that work in water?
How many per sqm you need this sensor in a field?
Can I use bluetooth instead of wifi for this?
How many such sensors are needed for an acre of land?
Please could you let me know what type of sensor the NPK sensor is? It is neither spectral nor optical? So which type is it?
where the simulation does
Do you have a full video for this research? I love to make it to help my father which is a farmer. If you have, can you tag me with it?
If I need to read the ph do you have any sensor?
There is already a dedicated tutorial on Soil Ph sensor. Check the channel videos.
Sir plzz tell me coast of this project I am farmer it is useful for me
The price list along with entire details is already shared in website article.
Cant we replace arduino nano board and esp32 module with node mcu?
Doesn’t work
my data is not showing in Thingspeak Server can u help me out
please tell me where I buy npk sensor
Visit the website article. The link for buyng NPk sensor is already given there.
Sir how much area cover or range of this sensor
Hello , It was a Nice Project. Can You tell on which platform you have simulated all the Sensors and Arduino. Thanks 🙂
Hi, where can i draw and download circuit diagrams online
How plant monitoring project using machine learning
hi just can u tell him how much total cost did u get in this particular project???
How do you power up the NPK sensor
12v
Nice project
Can i get the full video of this project?
How much an npk sensor cost?
Hi, Can you provide me a ready prototype of this device in working condition? How much would it cost? Please inform.
i am going to build this
Nice project.
Can anybody tell me how the sensor NPK sensors worked?
Hi there.. the power source is a bit of headache for me dc 9v .. possible to use a battery which type?
Use a 11.2V Lipo Battery
What is the cost of this project?
Tooo much !!!🤕🤕
Hi, your video is very helpful for my project. And, I need these as well
5. Magnesium
6. Lime
7. Silicon
8. Copper
9. Zinc
10. Manganese
11. Boron
12. Cation Exchange Capacity
Can you help me in finding these sensors?
Thank you
hi, do you find the sensors? i need to... tks
Why we required to transfer the dat from node to gateway?? we cant transfer data directly from node to thinkspeak using wifi module??
The sensor doesn’t work with nodemcu or esp32
thank you sir...
Can u provide link for the npk sensor. I want that sensor
Please visit the website article from link in description. You can get the purchase link from there.
Can I purchase whole project from you?
Hello ... can we make only a soil moisture sensor that can send a sms once the mositure value falls below a particular level ??
I would like to build this project, so can I buy the whole kit from you please @How To Electronics
The purchase link for all components are given in website article.
Amazing
Cost
IOt based Detection and Monitoring of Volatile and Semivolatile pollutants in soil. I want this project video
can you please give me the coding file please its urgent
Nice
❤❤❤
Pkese peice this project to implement
tnx
🤩🤩👍
