Could anyone shed light how the sensor actually works ? I understand the communication but what soil parameter it is measuring , when we try to measure N , or P or K for that matter ?
Hello Sraravanan. I've got zero for the third field of the receiveddataquery (refers to the number of valid bytes) and no changes in the captured data when i switch the sensor enviroment (normal to water to soil), what could cause these problems.
i already used your code but the output is different when i using your example the output always wrong i using weihan jxct 7 soil in one can you help me?
thank you for amazing video, it make me more know abou how to use that stuff. anyway, i already have that stuff *NPK 71n 1 Soil Sensor) but i can use it because i don't have other device (like chip and aplication fop computer) could you help to send me a shoping link to buy that chip ? thank you
Brother i am from Bangladesh. I watch your video. Previously you uploaded a gsm based motor controller board single phase . I want that type board for my irrigation pump motor. Tell me name of board and how i can get this? Please
Thank you for your efforts, but I'm using rs485 with DI,DE,RE,RO and the output readings is wrong .Is there away to use it instead of max13487.Thank you in advance
I intend to use this sensor but I don't have it yet. So I may be wrong about my conclusions so far. Looking at the schematic shown in the circuit drawing, the RS485 module is used instead of the MAX485 version that is physically shown in the video and has flow control (4 data pins: DI, DE, RE, RO). In the video this feature is mentioned (auto direction enable) and allows sending and receiving data between two Arduino boards (or another platform of the type). So the use of the MAX485 version is allowed but should not be mandatory. For beginners like me, this detail may raise doubts. Perhaps the soil sensor used has some incompatibility with the simple RS485 version. In this application, the RS485 module only receives data from the sensor and transfers it to the Arduino through digital ports 2 and 3, which are connected to the RXD and TXD ports of the RS485. Other boards identify these pins as DE and RE. To add to the confusion, the power pins (VCC and GND) are next to the pins that are connected to the sensor in the MAX485 version, and in the RS485 version shown in the drawing, the power is next to the data pins that are connected to the Arduino board. In the video, the MAX485 version shows the DI and RO pins connected, but in this application they are not used. When I can test the sensor, I will post the results.
True, it can't get the true values of NPK since the electrodes are not ion selective but use EC instead. EC is affected by total ions in aquaes solution.

Hi Saravanan
How do you calibate it?
hello sir
did you compare the received values with the actual tested soil values from soil laboratory
Indian don't compare and neither know of accuracy... They just make a videos a product either it works accurately or not they don't care or know
what do you think about this sensor accuracy ? have you test this sensor with other sensor ?
Hello, could you make a video which is the reading of several 7 in 1 sensors by RS485 protocol
Hello Sraravanan.
I've got zero for the third field of the receiveddataquery (refers to the number of valid bytes) and no changes in the captured data when i switch the sensor enviroment (normal to water to soil), what could cause these problems.
Could you please share the link to buy online MAX 13487 RS485 TTL ?
What do i do if i have no numbers recieving?
i have the rs485 to ttl you mentioned in the start (max485) is there any way to use it to interface the sensor with esp board ?
you can check this video with ESP32 ua-cam.com/video/kVBtNAe7tow/v-deo.html .Any RS485 to TTL with Auto Direct facility can be used
how to calibrate it?
Could I connect three of this sensors to one usb-rs485 receiver?
i already used your code but the output is different
when i using your example the output always wrong
i using weihan jxct 7 soil in one can you help me?
sir can u send me the over all program i have the product but i cant program it properly
Could I power three of this sensors with only one power supply? What voltage and Ampa will it need?
Eccellente video. Per lo sketch arduino per fargli leggere i valori, ed eventuali modifiche e aggiunte, dove posso scaricarlo? Grazie di cuore.

how to verify whether i am getting Correct NPK values or not

sir, i am not able to find this ma487 rs485 to ttl module anywhere, i request to provide some links

How is the result, does an rs485 work?😊
Hello Sir I need this sensor, do u still have it?
what is the power consumption of this sensor
Where i can find the datasheet?
What is unit of measurement
Hello sir nice video ,
Do you have pdf ,how to make or design this sensor ?
Sir please create detail video on leafwetness sensor
It's cool 🎉
sir can u giv me connection dia gram

Do Something About The Back Ground Noise. Could Not Finish The Video Had To Bail Out. You Got Yourself A Thumbs Down.
It's a fake sensor
Why?
@@prakashpoojary6116 Because it's based. on. EC. not. real NPK.
@@កសិកម្មនិងបច្ចេកវិទ្យា how do you know?
True, it can't get the true values of NPK since the electrodes are not ion selective but use EC instead. EC is affected by total ions in aquaes solution.
@@georgeolwal1087 But how can give a diferent measure on every ion?
hello sir
did you compare the received values with the actual tested soil values from laboratory
