Features & Capabilities

The Light Sensor Counter is a handy Chrome extension that continually monitors your device's light sensor and increments a counter each time a light threshold is crossed. Whether you want to count every time a light source shines or track interruptions in a light beam, this tool provides precise and versatile counting.

Key features include real-time illuminance readings in lux or foot-candles, detection based on rising or falling light levels, a no-count wait option to reduce double counts, and graphical visualization of illuminance values with count indications. Optional sound alerts accompany each count for user convenience. Note that sensor sampling speed and accuracy may vary across devices, so the readings serve as an estimate.

Perfect for developers, researchers, or anyone requiring a simple way to count light events using built-in device sensors.

User Reviews

The Light Sensor Counter app is appreciated for its useful functionality in counting light triggers, especially for DIY and electronic projects. Users find it works well for slow and ambient light changes. However, limitations include inability to use the back camera, missed counts during fast flashing lights, stopping counts when the screen is off, and lack of customizable sound notifications. Improvements such as options for camera selection, better detection of fast flashes, background counting, and enhanced UI were suggested to enhance usability.

Pros

Useful for counting LED light triggers and other light-based events.
Provides thoughtful options, suitable for electronic enthusiasts and DIY projects.
Works well for low frequency light detection and ambient light changes.
Simple and fulfills the basic functionality needed by users.
User-friendly interface appreciated by some users.

Cons

Uses front-facing camera only with no option to switch to the back camera, limiting functionality.
Inaccurate or missed counts for short, fast light flashes (e.g., blinking LEDs).
App stops counting when the screen is off or when the power button is pressed.
Limited sound notification options; sound is too quiet and not customizable.
User interface elements like borders take up valuable screen space on small devices.

This app uses the front facing camera as light sensor no settings to change to the main (back) camera on the mobilephone. Response rate is not good could be an OS issue. Tested with a blinking red LED. Misses many (>50%) of the short (250ms ie ¼s) flashes at 50% duty cycle.
