This paper describes the design and development of a passive wireless pH sensor tag. Under wireless interrogation, the sensor tag changes the phase of the interrogation signal according to the pH. The ...

Monitoring of pH is crucial for several chemical and biochemical processes. ISFET (Ion-Sensitive Field-Effect Transistors)-based pH sensors are promising candidates for pH monitoring applications.

The DS18B20 library supports only the DS18B20, only one sensor per pin, no parasite mode, no Fahrenheit and no alarm functions. The only feature the class supports is the asynchronous reading of the ...
