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 ?
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
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
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
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 I power three of this sensors with only one power supply? What voltage and Ampa will it need?
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?

Could I connect three of this sensors to one usb-rs485 receiver?
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.
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

Hi Saravanan
How do you calibate it?

Could you please share the link to buy online MAX 13487 RS485 TTL ?
Eccellente video. Per lo sketch arduino per fargli leggere i valori, ed eventuali modifiche e aggiunte, dove posso scaricarlo? Grazie di cuore.

It's cool 🎉

Hello sir nice video ,
Do you have pdf ,how to make or design this sensor ?
i already used your code but the output is different
when i using your example the output always wrong

Sir please create detail video on leafwetness sensor
sir, i am not able to find this ma487 rs485 to ttl module anywhere, i request to provide some links
how to verify whether i am getting Correct NPK values or not
Where i can find the datasheet?
how to calibrate it?
What is unit of measurement
what is the power consumption of this sensor
sir can u giv me connection dia gram
It's a fake sensor
Why?
@@prakashpoojary6116 Because it's based. on. EC. not. real NPK.
@@user-oy4rm9kr4t 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?
