Nightlights are tools for automatic illumination in dimly lit environments, greatly facilitating nighttime activities. However, current nightlights are all single-sensor type, only illuminating when a person or designated object is detected. In typical use, users in dark environments need to enter the nightlight's range to receive light. Often, due to limited sensing range or insensitive sensors, users have to wait for the next nightlight to illuminate before moving forward, or the nightlight may delay illuminating after someone has passed by, potentially leading to accidents due to delayed visibility.
