How inductive sensing (combined with capacitive sensing in some cases) enables a new level of smart surfaces with touch HMI.

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity ... so it is also good a good idea to try non-contact capacitive sensing method that can be used to ...

The capacitance detected will change depending on whether the liquid is near the sensor or not. This change is then converted into a digital high or low state using a comparator circuit. What is the ...

The capacitance signal is then input to the controller ... Fig 2 Block Diagram of the XKC Y25 NPN Liquid level Sensor Fig 3 Circuit Diagram of the proposed system Fig 4 Wiring of the proposed Liquid ...

This project shows how to build a liquid level ... described circuit can be used in many situations, e.g. for level measurement or as a leak detector. The circuit of the level switch is quite simple.
