Light Sensor Counter is a useful Android application developed by keuwlsoft. As the name suggests, it allows users to count the number of times a light source shines on the device's light sensor. This can be particularly handy for various purposes, such as tracking the number of times a light beam is broken.

The app provides illuminance values in lux (lumens per square meter) or foot-candles, giving users flexibility in their measurements. It offers the option to detect on both rising and falling past the detection level, ensuring accurate counting. Additionally, the app includes a feature to reduce double counts by enabling a no-count wait after detection.

Light Sensor Counter also includes a graph to visually display the illuminance values, making it easy to analyze trends and patterns. The counts are indicated on the graph and can be accompanied by an optional "click" sound for auditory feedback.

It's important to note that light sensors may vary in sampling speed, resolution, and accuracy across different devices. Therefore, the app serves as an indication rather than providing precise measurements.

With its user-friendly interface and practical features, Light Sensor Counter is a valuable tool for anyone needing to count light sources or monitor light beam interruptions.
