## Summary description

Solar sensor designed for use with RED module series RED-3 and RED-5. Provides solar irradiance detection and environmental light measurement for integration with compatible RED modules to enable solar-based control, monitoring or automation functions. Suitable for installation in systems that require external solar input for power management, shading or energy optimisation.

## Long description

The RED solar sensor is designed for integration with RED module series RED-3 and RED-5 to provide reliable measurement of solar irradiance and ambient light. Intended as an external input for compatible controllers and modules, the sensor enables systems to respond to changing sunlight conditions for tasks such as power management, shading control, and energy optimisation. The compact sensor delivers environmental light data to support automation logic and monitoring without requiring the module to perform direct radiometric measurements.
Advantages
The sensor provides accurate solar and ambient light detection tailored for seamless use with RED-3 and RED-5 modules. It simplifies installation and system integration by presenting standardized light data to the RED modules, allowing existing control routines to use solar input. The device supports outdoor placement and is built to deliver stable readings for shading, PV management, or energy-saving strategies, reducing the need for complex custom sensing solutions.
Suitable for
Shading and blind control based on solar irradiance
Photovoltaic system optimisation and monitoring
Building automation systems requiring external light input
Energy management and demand-side control strategies
Key specifications
Compatibility: designed for use with RED module series RED-3 and RED-5
Measurement: solar irradiance and ambient light detection
Intended installation: external/outdoor mounting for environmental light sensing
Output: sensor data formatted for integration with compatible RED modules
How to use
Mount the sensor in a location representative of the area you wish to monitor, avoiding shaded regions or nearby reflective surfaces that could bias readings. Connect the sensor to a compatible RED-3 or RED-5 module following the manufacturer’s wiring and interface requirements. Once connected, configure the RED module to read the sensor input and incorporate the measurements into control logic for shading, power management, or monitoring tasks. Verify readings after installation and adjust mounting position if measurements do not reflect expected solar conditions.
Usage recommendations
For reliable operation, place the sensor clear of obstructions and at a height and orientation that reflect the exposure of the area of interest. Periodically check the sensor for dirt or debris and clean the sensing surface as needed to maintain accurate measurements. When integrating with RED modules, confirm the module firmware and configuration support external solar sensor inputs.
