Goodd ay everyone.
I have bought this sensor module for pH and temperature sensors that used in my project.
However I couldn't use the temperature sensor.
Can anyone tell me the connection of T2 and T1 on the module to the arduino board?
I have problem with pH sensor too.
That is when the probe is inserted to a solution of pH 8.1, the reading of sensor is 7.4. When the probe is inserted to a solution of 9.4 it shows a reading of 6.3. ( i tested the solution with a pH meter)
How can i solve this question?
Please help. Thank you!
