Hello，
“The excitation source adopts an AC signal, which effectively reduces the polarization effect, improves the precision, and prolongs the life of the probe”
What this sentence means is that we use AC to excite the probe on the adapter board. It's not that you use AC to power the sensor. The sensor could only be powered in DC(3.3~5V).
Regarding reduce polarization, we're sorry, but this belongs to our R&D team's encrypted information. We can't make it public.
We hope this information could help you out.
JaneYu Okay, but why my salinity sensor always decreases after calibration (unstable)? Can u help me?
Note : Solution salinity what I have 10-20 ppt, but this sensor read <10 ppt.
Thank you!
Like we reply in our email, we think the ERROR might occur when your EEPROM has an old data.
JaneYu How to fins a blueprint for the sensor, some wire has dissontect inside the probe.
JaneYu Sorry, the schmetic for the board is not opensource.
If you have doubts when using the sensor, you can send us an email.
We will provide you with after-sales service once we found out that it is a faulty product
Hello, is it possible to make the probe wire longer, for example, 3 meters?
JaneYu Hi, We do not recommend extending the cable by yourself. If necessary, try to use high-quality cables and do not connect them too long. Otherwise, partial pressure may be generated on the cable and the reading accuracy will be affected
My results are 1.9 even i applied the reset code. When i put it in the solution it is still read at 1.9 and the lowest is 0.3 i triedany calibration method from youtube and it doesn't work. Do you think it is possible that the probe or sensor is deffective?
JaneYu Hi,
I have a k10 probe, I can't calibration process, indeed one time I had accomplished calibration but now it does not calibrate, it always shows wrong values, could you help me, what can I do? Thank you.
JaneYu Please contact our technical support email: [email protected]
Hello you, I want to buy Analog Electrical Conductivity Sensor / Meter(K=1) . IF you transport to ho chi minh city, how much does transportaion cost ?
how long days for shipping ?
JaneYu Hello Luara.
It's hard to identify the problem without more details. Let's make sure that you follow the calibration process carefully and your code is bug free. If it still outputs 0, please reach us with your code and more details about the problem at [email protected]
JaneYu Hi, this sensor couldn't put in water for a long time or it will shorten the service life.
JaneYu Hi, can the EC sensor or TDS sensor used for 24/7 measurement? Is there a industrial version of it?
JaneYu Sorry, maybe there is some issue about the display and have a try with this code.
#include <eeprom.h>
#define KVALUEADDR 0x0F
void setup(){
for(byte i = 0;i< 8; i++ ){
EEPROM.write(KVALUEADDR+i, 0xFF);
}
}
void loop(){
}
JaneYu Sorry, we sell it in whole kit.
JaneYu Ok, thank you.
So, can we buy just the shield ?
Regards
Hi, I got the K=10 and I'm measuring marine water for my aquarium. According to my refractometer, my water has a salinity level of 35,000 ppm, which represents 53.0 ms/cm at 25 deg Celcius. However, the sensor is showing MUCH lower, about EC:7.33ms/cm
...I have a temperature sensor attached, I'm using your libraries and I did the calibration. What am I doing wrong?
JaneYu Is temperature compensation done?
Is the exitec command entered after calibration with the calibration solution, is the calibration value around 12.9?
Temperature compensation method:
In the DFRobot_EC10 software library, the temperature compensation algorithm has been integrated. You only need to pass the voltage value and temperature value into the float readEC (float voltage, float temperature) function to obtain the conductivity value after temperature compensation. Therefore, to ensure accuracy, it is highly recommended that you add a temperature sensor and read the temperature value of the solution to perform automatic temperature compensation.
Hello, I used the K = 10 library. I tryed to calibrate my probe but it always says buffer solution error failed try again. What am I doing wrong?
JaneYu Sorry, the wiki for this product has not been translated into English. I will give you a link of Chinese wiki, and you can use code on wiki page.
K=10 Chinese wiki link: http://wiki.dfrobot.com.cn/...
K=10 libraries' download link: https://codeload.github.com...
JaneYu Hello, this library work well. Thank you
I have bought EC Dfrobot K = 1. can you tell me how to convert code to micro siemen / cm?
JaneYu can you tell me the different the K value of K=1, K=2, K=10,etc ?
what's function the K value for the measure?
JaneYu The K value is to represent character of different probes, different K value can measure different EC range, normally K=1 measures 1.0～2000μS/cm, K=10 measures 10～20000μS/cm
Any improvement to electrical isolation with this unit and say a pH sensor?
JaneYu
