Human Infrared Sensor Switch (PIR Motion Sensor Bulb Holder).
No switch is required to turn the light on and off. As a result, lights are never left on unnecessarily, saving electricity bills.
Where to use: It is best suited for stairwells, bathrooms, balconies, store rooms, or garages where people are not constantly present, but light is needed when they enter.
You can set how many seconds or minutes the light stays on after a person leaves the sensor's range (e.g., 30 seconds to 5 minutes).
Lux (Light Sensor): This allows you to set whether the sensor will work only at night/in the dark, or day and night always.
