A Zigbee daylight sensor comes in several types. They utilise the Zigbee communication protocol to measure ambient light and integrate into smart lighting systems. Here are the most common options.
These sensors use digital light measurement technologies. They offer high precision and can measure ambient light levels to moderate or high accuracy. They are mainly used in high-end lighting control and automation systems.
These are compact daylight sensors. They detect light levels using photodiodes, which convert light into electrical current. Though not as advanced as digital sensors, they are cost-effective for basic light level detection and are common in budget-friendly systems.
Daylight sensors specifically designed for skylight or window applications are called smart skylight sensors. They monitor light levels coming through skylights or windows. It helps control shading systems to reduce glare and manage heat. Commonly found in architectural integration and building management systems, these sensors ensure occupant comfort.
Some sensors combine motion detection with daylight detection. They save energy by turning on artificial light only when natural light is insufficient and when presence is detected. These devices detect both presence and light levels. They are popular in commercial settings where both occupancy and daylight levels need optimisation.
These help with indoor applications. They continuously monitor light levels in interior spaces for optimal lighting control. The main function is to adjust artificial lighting based on available natural light. They are mostly used in residential and commercial environments for comfort and energy efficiency.
