What is Stray Capacitance? Stray capacitance, also known as parasitic capacitance, refers to the unintentional and unwanted capacitance that exists between conductors in an electronic circuit. This capacitance arises due to the proximity of conductors, the presence of dielectric materials, and the geometry of the circuit layout. In an ideal world, electronic components would behave…

What are Proximity Switches? Proximity switches, also known as proximity sensors, are devices that detect the presence or absence of an object without physical contact. They operate by emitting an electromagnetic field or beam of electromagnetic radiation and detecting changes in the field or return signal caused by the presence of an object. Proximity switches…

What is a pH Sensor? A pH sensor is a device that measures the hydrogen ion activity in a solution, indicating its acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral, values below 7 being acidic, and values above 7 being alkaline or basic. The term “pH” stands for…
