I am interested in making a light-sensing circuit that can automatically respond to changes in brightness. For example, such a circuit could be used to adjust screen backlight brightness, control smart home lighting, or serve as part of an environmental monitoring system in an IoT setup.
The TEMT6000 is an ambient light sensor based on a silicon phototransistor. It outputs an analog voltage proportional to the intensity of visible light, with a spectral response curve close to that of the human eye. Because it works at 3.3V–5V and provides a linear analog output, it seems straightforward to connect it directly to a microcontroller ADC input.
Can the output of the TEMT6000 be reliably read by an Arduino analog input without additional circuitry, or is it recommended to use filtering or amplification to ensure stable results in practical applications?
