The LTR-308ALS-01 is an ambient light sensor manufactured by Lite-On. It is a light-weight, low power consuming ambient light photo sensor with a detection range of 1 Lux to 10000 Lux. A photo diode is used as a light-detecting element, and an integrated amplifier circuit provides a linear output voltage with maximum sensitivity. The LTR-308ALS-01 is designed in such a way that it can detect visible, UV, and IR light sources. It is able to detect sunlight, artificial light, and other light sources. It features low dark current and low temperature-dependent characteristics. It also has an adjustable sensitivity range and a fast response time. Moreover, this device is resistant to noise, dirt, moisture, and dust. It can be used in lighting control systems, level detection, and ambient light measurement.
