The digital light sensor (ALS - Ambient Light Sensor) must be taken into account for precise light measurements. In addition, the LTR-507ALS also measures the proximity (PS - Proximity Sensor) of the object to the sensor. All this data is sent via I2C communication, which is easy to read via our Arduino library.
