## Description

Measure light intensity instantly with your device&#39;s ambient light sensor. Lux Meter displays real-time illuminance in lux, foot-candles (fc), and EV values through a clear visual gauge ranging from Dark to Moderate to Bright.<br><br>INSTANT ILLUMINANCE MEASUREMENT<br>Get instant lux readings the moment you open the app. The live gauge shows current light levels with numerical readouts in lux, foot-candles, and EV. Use Lock to freeze a reading, Reference to set a comparison baseline, Save to store measurements, and Switch between units.<br><br>LIGHTING STANDARDS COMPLIANCE<br>Check whether your space meets recommended lighting standards for specific environments. Built-in references include Office (300-500 lux), Classroom (300-500 lux), Library (500+ lux), and Hospital Ward (100-200 lux). Quickly verify if a room&#39;s illumination falls within the acceptable range for its intended use.<br><br>PLANT LIGHT CALCULATOR (DLI)<br>Calculate the Daily Light Integral (DLI) in mol/m2/day and Photosynthetic Photon Flux Density (PPFD) in umol/m2/s to determine if your plants are receiving adequate light. Check compatibility for common houseplants: Monstera (5-8 mol), Snake Plant (3-6 mol), Fiddle Leaf Fig (6-12 mol), and Tomato (20-30 mol).<br><br>CONTINUOUS LIGHT MONITORING<br>Record light levels over time with the built-in monitoring mode. A real-time trend chart updates at 1-second intervals, tracking Min, Avg, Max values and total sample count. Use the timer to run timed recording sessions and review the data afterward.<br><br>Whether you need to verify workplace lighting, optimize indoor plant growth, or log ambient light conditions, Lux Meter provides the measurement tools you need in a straightforward interface.
