AMBI Light Sensor

We have cooked up this tiny sensor board called “AMBI” (for ambient light sensor) that carries a Sharp GA1A1S201WP surface-mount ambient light sensor. The AMBI’s 3-pin interface can mount directly into the analog pins on an Arduino (since the sensor draws under a milliamp the other two pins are used to provide power).   The light sensor has a spectral response similar to that of the human eye, which means the sensor is highly accurate when used as the basis of an ambient light sensor, and can capture an astonishingly wide range of light values (3 to 55000 lux). It performs very similarly to a light meter, and will be useful in a wide range of light sensing applications.   The sensor works at up to +7V, or down to 3 volts, and operates accurately across a wide temperature range between -40 and +85 C. This is a light sensor that we've been waiting for, for a long time. If you use photo cells or phototransistors, or other light sensors such as the useful TAOS TSL series, you know that eve
