1. Fingerprint collection: Place yourfinger on the fingerprint recognition component, and a preset capacitive sensoror photoelectric sensor will read the shape of the fingerprint and save it as adigital signal. 2. Digital signal processing: The processoranalyzes and processes digital signals, and comp...
As the name itself specifies that the resistor that depends upon the light intensity. It works on the principle of photoconductivity which means the conduction due to the light. It is generally made up of Cadmium sulfide.When light falls on the LDR,its resistance decreases and acts similar to ...
1. Capacitive touch sensor A cap touch sensor works by detecting the change in capacitance between the two sides of the sensor when there’s pressure on one side. The pressure causes a slight change in the electrical charge between two metal electrodes on each sensor side. So capacitive touch...

IV Classification and Working Principle of Infrared Sensors Infrared sensors can be divided into thermal sensors and photonic sensors. 1. Thermal Sensors The thermal detector absorbs all the incident radiation energy of various wavelengths. It uses thethermal effectof radiation to cause a temperature ri...
Inductive sensors only detect metal, while capacitive sensors also detect non-conductive materials such as glass, liquids and plastics. Operation of both is non-contact: Inductive sensors use magnetic fields under influence of metallic objects, while capacitive sen...
