What is the maximum range achievable by a typical infrared LED?

The maximum range achievable by a typical infrared LED is up to 1 km in free space conditions. This range is based on the properties of infrared light, which can travel longer distances in unobstructed environments free from interference and atmospheric absorption. In free space, infrared light can maintain its intensity over longer distances, making it suitable for applications like remote sensing and communication.

Influencing factors such as the power of the LED, the wavelength of the emitted light, and environmental conditions play vital roles in determining the effective range. In ideal situations with minimal atmospheric interference, a typical infrared LED can produce a strong enough signal to reach this distance.

While other ranges mentioned may seem plausible under certain circumstances, they generally do not reflect the typical performance expected from an infrared LED in optimal free space conditions. Therefore, the accurate representation of maximum range is indeed up to 1 km.
