Working and Functional Block Diagram of E18-D80NK

E18-D80NK is a variable range non-contact detection sensor. It comes with a transmitter and receiver in a single module setup. The transmitter emits a modulated IR signal which is reflected by the object in its field of view or the path and the reflected signal is then collected by the transmitter, providing a digital output to the microcontroller.

E18-D80NK Block Diagram

As we can observe in the block diagram, the technology behind this module uses modulation from the infrared light and the receiver part only detects the infrared light when it collects the correct signal. Hence, cutting down on collecting all the interferences from the nearby surrounding lights.
