Solar sensor for RED modules RED-3 / RED-5 by RED

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.
