The Wire Daylight Sensor is a precision device designed to monitor ambient light intensity and automatically adjust lighting scenarios in response to changing environmental conditions such as smog, fog, or smoke. It ensures optimal lighting levels throughout the day and maintains visibility even when atmospheric conditions reduce natural light. The sensor is particularly suited for integration into luminaires or other lighting infrastructure, providing intelligent control and adaptability.
Data communication with other devices is primarily achieved through an RS-485 interface using the Modbus-RTU protocol, enabling reliable and fast integration with control systems. Certain versions of the device also support wireless data exchange via mobile communication, extending flexibility in remote installations. The sensor features an embedded GPS receiver, allowing precise location tracking and synchronization for large-scale deployments.
The unit is powered by AC networks with a voltage range of 100 to 250 V and consumes a maximum of 5 W, while supporting loads up to 1000 W. It is configured remotely through the control system, eliminating the need for manual adjustments on-site, and includes LED indicators to provide clear operational status at a glance. The device is mounted using wire connections, making installation inside luminaires, on poles, or similar structures straightforward. Its solid plastic housing is rated IP66 for dust and water resistance, ensuring reliable operation in harsh outdoor environments.
Mechanically, the sensor has compact dimensions of 87 mm in diameter and 91.3 mm in height (69.3 mm excluding mounting), with a lightweight construction of 0.2 kg. It is designed to operate in extreme environmental conditions, with an operating temperature range from -40 to +70°C and storage tolerance from -50 to +80°C. The device can withstand full relative humidity and is CE compliant, RoHS certified, and backed by a 36-month warranty.
Connectivity options include the standard RS-485 interface and an optional GSM radio channel supporting frequencies of 850, 900, 1800, and 1900 MHz. All input and output connections are made via wires, and the sensor itself contains an embedded light sensor. Remote setup is carried out via software, while LED indicators provide immediate operational feedback. The package includes the Wire Daylight Sensor unit, ready for installation.
