Light Sensor Counter description

The light sensor in your device is continually monitored and when the detection level is crossed, the counter is increased by one.

Can be used to count each time a light source shines on the sensor. Or alternatively, shine a light on the sensor and count each time the light beam is broken.

• Illuminance values in lux (lumens per square meter) or foot-candles.

• Detect on rising or falling past the detection level.

• Reduce double counts with optional no-count wait after detection.

• Graph to show illuminance values.

• Counts indicated on graph and with optional 'click' sound.


Light sensors will vary in sampling speed, resolution and accuracy from one device to the next. For indication only.
