Capacitive Sensor : Formula, Working , Types, Circuit, Interfacing & Its Applications
A proximity sensor is an electronic device, used to sense or detect the presence or approach of nearby objects without physical contact. So these sensors change the data on the object’s presence or movement into an electrical signal. Generally, detection systems are available in three types of systems that perform this conversion. The systems that utilize the eddy currents that are generated within metallic sensing objects through electromagnetic induction, the systems that notice changes within … [Read more...]
