DESIGNING A PH DATA ACQUISITION and LOGGING DEVICE USING AN INEXPENSIVE MICROCONTROLLER
ABSTRACT
Accurate measurement and analysis of pH data is required for a multitude of applications ranging from the agricultural sector to clinical laboratories. In many of these applications an inexpensive hand-held unit is needed.
This paper describes a low cost and low power pH sensing and data logging system using a Renesas microcontroller and pH sensor.
This paper describes the sensor data acquisition and data logging system including details of its construction, capabilities and applications.
