App Description
Measures light with high/low limits alarm & statistics. Converts lux to PPFD/DLI
Measures ambient light using your smartphone's sensor. Professional lux meter with ranges from 0-800 to 80000 lux, adjustable speed, calibration, and high/low limit alarms. Converts lux to PPFD and DLI with 16 light sources. Ideal for photography, indoor agriculture, and lighting design.
Requires ambient light sensor. Accuracy depends on your device's sensor quality. Use calibration to adapt readings to your specific hardware.
PROFESSIONAL LIGHT MEASUREMENT:
Operating Ranges
• 0-800 lux (dark environments)
• 0-8000 lux (indoor and offices)
• 0-80000 lux (outdoor and direct sunlight)
Measurement Speed
• 5 Hz (slow, stable readings)
• 10 Hz (standard)
• 20 Hz (high speed for rapid changes)
Custom Calibration
• Adjust with reference factor
• Compensates for sensor variations across different smartphones
• Saves your calibration for future measurements
SMART ALARM SYSTEM:
High/Low Limits
• Set custom minimum and maximum limits
• Sound or vibration alarm when limits are exceeded
• 20 presets with standard lighting limits
• Perfect for quality control and continuous monitoring
VISUALIZATION & ANALYSIS:
Main Meter (Arc)
• Continuous or segmented mode
• Dynamic color based on intensity
• Intuitive analog reading
Center Value
• Shows current value in lux (large and clear)
Secondary Meter
• Shows same value in foot-candles (fc)
• Automatic real-time conversion
Real-time Statistics
• Maximum recorded value
• Average value
• Minimum recorded value
Historical Graph
• Stores up to 100 readings
• Real-time curve
• Limits are shown on the graph
• Easily identify out-of-range readings
LUX → PPFD → DLI CALCULATOR:
16 Preconfigured Light Sources
• Sunlight
• Fluorescent lamp
• CMH (Metal Halide lamp)
• D50 (Standard for graphic industry)
• D55, D65, D75
• LED 3000K, 4000K, 5000K, 6500K
• HPS (High Pressure Sodium)
• Incandescent lamp
• Plant grow light (horticulture)
• Standard office light
• Custom light spectrum
Automatic Conversion (using sensor)
• Converts lux to PPFD based on selected source
• Calculates DLI (Daily Light Integral) by entering time
• Ideal for indoor agriculture and horticulture
Manual Conversion
• Enter any lux value
• Select hours of exposure
• Get instant PPFD and DLI results
PRACTICAL USE CASES:
Photography & Video
• Studio lighting control
• Ambient light measurement for correct exposure
Indoor Agriculture / Grow Rooms
• Measure PPFD for plant cultivation
• Calculate DLI to optimize light cycles
• Adjust lamp height based on readings
Lighting Design
• Verify light levels in offices and commercial spaces
• Meet lighting regulations
Quality Control
• Monitor production lines
• Verify lighting uniformity
Horticulture & Gardening
• Measure light in greenhouses
• Optimize plant growth
IMPORTANT:
• Accuracy depends on your device's light sensor
• Calibrate with a reference lux meter for best results
• The front (proximity) sensor is NOT the light sensor
• Verify that your smartphone has an ambient light sensor
This app is ideal for lighting professionals, photographers, indoor farmers, engineers, and gardening enthusiasts.
