Optical sensors refer to sensors that react to light in the form of radiant energy such as infrared (IR), visible, and ultraviolet (UV). Photo detectors are a type of optical sensor that convert incident light into an electrical signal. Amongst these, a remote receiver (EAIRMIA1) works in a slightly different way. In this article, the application field and working principle of the EAIRMIA1 will be discussed.

The application of EAIRMIA1 is in line-of-sight applications. It is used for long-distance communication, for example between a remote control device and a television. Here, it is positioned at the end of what is referred to as a "line-of-sight connection". This connection is a continuous optical transmission of information from a source to a destination. Essentially, the EAIRMIA1 is the receiver of the information.

In terms of its working principle, EAIRMIA1 can sense changes in the amount of infrared light on the receiver surface. Light is driven to the receiver by an IR diode; the reflected IR light from the target is acquired by an optical lens and launched onto a photodiode. The current at the output of the photo diode varies based on the amount of infrared light detected. By monitoring the current at the output, the receiver can track changes in light detected, such as from an incoming direction.

The primary components of EAIRMIA1 are the emitters-receivers, controller circuits, optical devices and photodiodes. The controller circuits are responsible for the output of the detected signal, and are composed of several components such as an infrared controller and a filter circuit. In addition, the optical devices include lenses, a photodiode and other lens assemblies. The photodiode is what captures the infrared light from the lens and converts it into an electrical signal.

The EAIRMIA1 can be programmed for sensitivity and response characteristics. It is designed to reject alternating current signals of frequencies higher than the infrared transmission frequency and thus transmit the signal from the remote control. The frequency of the signal can be adjusted by the controller circuit and the sensitivity of the receiver can be adjusted by changing the ratio of the optical devices. This allows for a better response to the incoming signals.

In summary, the EAIRMIA1 is used as a remote receiver for line-of-sight communication. It detects changes in the amount of infrared light on the receiver surface and converts it into an electrical signal. It is composed of emitters-receivers, controller circuits, optical devices and photodiodes, and can be programmed for sensitivity and response characteristics. EAIRMIA1 is proving to be an increasingly important tool in many applications and hardware applications.
