Global Capacitive Sensor Market Research Report & Analysis 2033
A capacitive sensor is a type of proximity sensor that detects the presence or proximity of objects by measuring changes in capacitance. It operates based on the principle that every object has capacitance, which is the ability to store an electric charge. When an object comes close to the sensor, the capacitance between the object and the sensor changes, allowing the sensor to detect the presence or proximity of the object.
Working Principle: Capacitive sensors consist of two conductive plates separated by a dielectric material, such as air or a non-conductive surface. An oscillating electrical field is created between the plates, forming a capacitor. When an object enters the sensing area, it disrupts the electric field, causing a change in capacitance. This change is detected by the sensor, triggering a response.
