AMSKY01

Sky brightness sensor with mag/arcsec² output

16×12 pixel IR cloud sensor (32×24 available)

Precision temperature & humidity sensor

Dual interface USB-C & RS485

ASCII protocol for easy integration

Designed for autonomous observatories

AMSKY01 is a professional sky quality sensor designed specifically for autonomous and remotely operated observatories.

Unlike traditional single-point cloud detectors, AMSKY01 features a 16×12 pixel MLX9064x thermopile array that provides detailed sky temperature mapping for precise cloud detection and sky clarity assessment. Combined with an optical sky brightness sensor (outputting both lux and mag/arcsec²) and SHT41 environmental sensor, it delivers comprehensive weather monitoring in a single compact unit. A high-resolution 32×24 pixel variant is also available for enhanced spatial analysis.

With dual connectivity options (USB-C CDC serial and RS485) and an ASCII text-based protocol, AMSKY01 integrates seamlessly into observatory automation systems, SCADA networks, and custom monitoring solutions.

Key Features

Pixel Matrix Thermopile Array (MLX9064x) Advanced 16×12 pixel IR sensor (32×24 variant available) provides detailed sky temperature mapping for superior cloud detection compared to single-point sensors. Enables spatial analysis of cloud coverage and sky conditions.

Optical Sky Brightness Measurement Dual-output photometric sensor delivers real-time readings in both lux and mag/arcsec² units for standardized sky quality assessment and light pollution monitoring.

SHT41 Environmental Sensor Precision-calibrated temperature and humidity measurement for comprehensive meteorological data collection.

Flexible Power & Connectivity USB-C (5V bus-powered) or external 8-13V DC supply. Dual interface: USB CDC serial for plug-and-play operation, or RS485 for industrial-grade long-distance communication.

ASCII Text Protocol Simple, human-readable command structure enables rapid integration into existing automation systems without complex parsing libraries.

Outdoor-Rated Design Weatherproof enclosure engineered for continuous 24/7 operation in permanent observatory installations.

Cloud Detection in Action

The following video shows real-time data from the AMSKY01 sensor as cloud coverage develops overhead. The 16×12 pixel thermopile array captures detailed sky temperature distribution across its 110° field of view, enabling precise detection of cloud movement and coverage patterns. Watch how the sensor responds to changing atmospheric conditions in real-time.
