i am trying to calibrate my ph sensor using arduino uno... the coding was taken from atlas scientific... Even i hv folow al the steps according to manual still it shows the same reading...7.05 even for acidic and alkaline solution...solutions dat came wit the sensor...Is there any possibilities the sensor to be fail or the coding???

Maybe can check the tech support of Atlas Scientific here: http://atlas-scientific.com/support.html

did u sent command from arduino or computer to do calibration and command to read continuous from PH sensor?

Yeap...i send command through arduino....using arduino uno

hmm.. not sure what is the problem. mayb you try recalibrating the sensor? can you post the arduino code you write here?

I just use once this sensor. Just send serial "c\r", then the output is coming out. See Lesson pH Sensor.

I am using arduino uno. dats the controller dat m using on. i took the coding from atlas-scientific for arduino. Still the reading are juz the same. I use the manual given by atlas-scientific for the calibration steps and wiring al
Bt still couldnt calibrate. the reading still shows 7.05
