Free chlorine detection is crucial for ensuring water quality and public health. The field encompasses a wide range of sensing approaches, including electrochemical, optical and sensor array ...
Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...
T his article is a follow-up to the one on SELF capacitance [1], and together, they cover the theories and design guides for the two most popular capacitive sensors, the projected and self capacitive ...
