Turn your Android device into a professional lighting reference tool. Light Sensor Test reads your device's ambient light sensor in real time and compares the measured illuminance against the recommended levels defined by ISO 8995-1 — the international standard for indoor workplace lighting.
Key features:
• Real-time illuminance reading in lux (lx) • Color temperature measurement in Kelvin (K) using the device camera • Reference values for a wide range of building types and areas (offices, corridors, warehouses, hospitals, schools, and more) • Visual indicator showing whether the current light level is within the recommended range, too low, or too high • Based on ISO 8995-1 good-practice guidelines
Who is it for?
Facility managers, architects, engineers, students, and anyone interested in evaluating the lighting quality of indoor spaces — without the need for a dedicated lux meter.
Disclaimer:
The reference values displayed are based on ISO 8995-1 and are provided for informational purposes only. They do not replace a professional lighting assessment or compliance with applicable local regulations.
