I dont need to calculate . According to your error with the standard solution, get the difference value, extend the range, it will be ok. If you want to set more larger value, its also ok. Wendy.Hu

2016-09-29 04:43:28 How did you calculate the calibration range i.e. (factorTemp>0.55) && (factorTemp<1.45)? Private Ltd Implantaire Technologies (I)

2016-09-29 03:23:16 Thank you:) it worked. Private Ltd Implantaire Technologies (I)

2016-09-29 02:37:28 Hi Sir，

Maybe the error beyond the range of calibration, you can modify the code to extend the range:

eg: if((factorTemp>0.55) && (factorTemp<1.45)),etc.

2016-09-28 22:50:05 Hi, I was able to run the meter.

But, need to calibrate! the values are 10 to 11 ms/cm for the 12.88 ms/cm solution & 1.07 ms/cm for 1.41 ms/cm solution.

I tried to calibrate it with the Calibration code from the "github" but when i send "confirm" from the serial monitor it displays "Confirm Failed,Try Again". Any suggestions? Private Ltd Implantaire Technologies (I)

2016-09-28 20:49:36 Should the baud rate be 115200? can't i use 9600 baud rate? Private Ltd Implantaire Technologies (I)

2016-09-27 23:09:54 Did you do a test according to our wiki? And did you choose the baud rate correctly in monitor? 115200? Wendy.Hu

2016-09-27 21:04:33 Yeah. If i run only the Water temperature code then it works fine. but if i connect the EC sensor along with the temperature probe as mentioned in the DFROBOT wiki it will Display some random unreadable text. Private Ltd Implantaire Technologies (I)

2016-09-18 22:04:31 Hi Sir,

Can you give me more detailed info about your trouble? You mean the value you get is wrong, right? Wendy.Hu

2016-09-16 22:26:10 Hi, I'm getting garbage value in the serial monitor when i run the sample code of the DFR0300 EC meter. the interfacing is as per the instruction given in wiki. Need help!!!! Private Ltd Implantaire Technologies (I)
