Proximity Sensor
The proximity sensor includes a light-emitting element (Emitter) and a light-sensing element. The light-emitting element emits a light signal to the sensing object. After part of the signal is reflected, the light-sensing element captures and processes the reflected light signal, and then transmits it through the amplifier. The analog-to-digital converter amplifies and converts the signal into a digital signal, and the subsequent circuit knows the distance between the object and the sensing chip according to the algorithm, so that it can be used for various proximity sensing applications.
