The MSA01 Ambient Light Sensor is a smart light intensity sensor designed for precise lux measurements in various environments.Using a high-sensitivity photodiode and photopic spectral filtering, it measures illuminance across a wide 1–54,388 Lux range. Data is broadcast at configurable intervals via Bluetooth LE 5.0. The integrated tamper switch immediately sends alerts upon removal, providing continuous monitoring. Installation is tool-free with industrial adhesive backing, making it ideal for smart homes, 辦公室, commercial lighting, agricultural greenhouses, laboratory environments, and cultural heritage applications.

What is Lux Level?

勒克斯, often referred to as “foot-candles,” quantifies the amount of natural or artificial light striking a surface. While lumens measure the total light output, lux indicates how much of that light actually lands on a given area.In practical terms, one lux equals one lumen per square meter (1 lm/m²). So if a light source emits one lumen and that light is distributed evenly across a one–square-meter surface, the illuminance on that surface is one lux.

Wide Range Brightness Detection

With a measurement range of 1 到 54,388 勒克斯, the MSA01 is built to adapt across diverse lighting environments—whether it’s maintaining ideal conditions in museum archives (≤200 Lux), optimizing office lighting (300–500 Lux), regulating greenhouse growth zones (800–2000 Lux), or monitoring retail displays and outdoor areas (10,000–50,000 Lux). This wide dynamic range ensures stable brightness awareness across indoor and outdoor applications alike, delivering reliable data where lighting precision matters most.

Spectral Accuracy

The MSA01 is engineered for perceptual precision. Its optical filters and photodiode are tuned to closely match the human eye’s photopic sensitivity curve, which peaks at 555 nm, while the MSA01’s response curve peaks at 560 nm—a remarkably close match. This alignment ensures that the sensor reports not just raw illuminance values, but perceived brightness with high fidelity.

Such spectral accuracy is vital for museum exhibits, lab environments, and human-centric lighting systems, where accurate interpretation of light as humans see it is essential.

Customizable Threshold Alerts

Beyond raw brightness readings, the MSA01 allows you to define a single custom light threshold—such as 10,000 Lux for vegetable greenhouses during growth periods. When the measured light crosses this predefined threshold, the device broadcasts a special alert frame, enabling automated actions like dimming, alarms, or system notifications. This makes real-time response simple and effective for light-critical environments.

Anti-Tamper Security

A built-in tamper switch detects any unauthorized removal or impact. The moment it’s tripped, the MSA01 elevates its broadcast rate to 1 s intervals (為了 30 s) on the “Tamper” channel, ensuring security systems and administrators receive an immediate notification.

無縫集成 & 配置

Equipped with both BLE broadcast, the MSA01 plugs effortlessly into cloud gateways, building‐management systems, or edge controllers. Factory pre-pairing and its zero-config adhesive mount mean you can deploy dozens of units in minutes, not hours.

Exceptional Signal Stability

Fluorescent and LED lighting often introduces 50Hz/60Hz flicker—an invisible form of noise that can distort ambient light readings. The MSA01 is engineered with intelligent signal processing that actively rejects low-frequency light fluctuations, delivering clean, consistent lux measurements even in electrically noisy environments. This ensures lighting control systems, lab monitors, and heritage protection setups rely on stable, trustworthy data at all times.

應用場景

  • 智慧家庭 & 辦公室

    Create a Comfortable, Productive Space
    Lighting directly affects visual comfort and work efficiency. Integrated into curtain rails or hallway lighting modules, the MSA01 automatically turns on lights or opens curtains when ambient brightness drops below 300 勒克斯, helping maintain a bright and inviting workspace.
    ≥500 Lux for general desks; ≤1000 Lux for precision tasks.

  • Commercial Lighting & Displays

    Showcase Products in Their Best Light
    在零售環境中, lighting not only enhances product appeal but also guides customer flow. The MSA01 keeps display areas within the ideal 1500–2000 Lux range and adjusts to ambient changes to ensure consistent presentation.
    3000–4000 Lux for fashion or jewelry displays; 300–500 Lux for produce and daily goods.

  • Smart Agriculture Greenhouses

    Support Healthy Growth with Reliable Lighting
    Light is vital to the growth cycle of plants and livestock. Installed in greenhouses or barns, the MSA01 monitors natural and artificial lighting, triggering supplemental light when intensity falls below crop-specific thresholds (例如, <800 勒克斯).
    20,000–30,000 Lux for strawberries; 5–20 Lux for poultry rearing stages.
    Smart Agriculture Greenhouses

  • Laboratory Light Monitoring

    Maintain Controlled Lighting for Reliable Results
    In laboratory settings, maintaining appropriate lighting is key to accurate observations and sample protection. The MSA01 monitors light exposure around sensitive equipment, helping prevent over-illumination that may affect experimental outcomes. Suitable for incubators, test chambers, and cleanrooms, it supports consistent research conditions.
    ≤200 Lux for light-sensitive experiments; 500–750 Lux for general laboratory tasks; ≥1000 Lux for inspection and clean zones.

  • Cultural Heritage Preservation

    Protect Priceless Artifacts from Overexposure
    In museums and archives, long-term light exposure can degrade delicate items. The MSA01 continuously monitors display lighting, ensuring levels remain below 50 Lux to protect artworks and historical documents. Automated dimming keeps exhibits safe while maintaining visibility.
    ≤50 Lux for paper-based materials; ≤150 Lux for paintings and textiles.
