Sensor based electronic circuits design projects and schematics
A touch switch sensor can be designed using this simple electronic circuit. The touch switch sensor is built using a CMOS circuit, a resistor and a capacitor.
This humidity detector circuit diagram is very simple and uses few components and can be used for activation of an electronic devices when the detector senses a certain humidity.
A touch sensor switch circuit that works with 10 channels can be designed using electronic scheme in the figure below. If one of the 10 sensors is touched, the corresponding output goes in a logical state 1, the other inputs are in logic state 0.
