Hello, I am using an arduino uno R4 wifi with a temp sensor ( would like to read the external temp DS18B20 and a ph sensor with a 4502c module and on this module, there is a temperature sensor...
The system is for my swiming pool, I can retrieve the temp of the water and its PH... ans I would like to retrieve the external temp... I could use a second DS18B20 sensor of course, but I would like to use the one one the 4502c module and I don't know what to do with it??? if I read le value on this pin, I retrieve something like 733... I don't find any info on the web except a 4502C arduino library in witch, the temp is just the analogRead...
Any idea?
