Visible light sensor,photodiode,optical sensor:
A low cost visible light sensor, with a current output which is directly proportional to the light level. It has a built in optical filter to provide a response which is close to the human eye, or photopic. The output current can be converted to a voltage by connecting it in series with a resistor. The dynamic range is determined by the external resistor and power supply (10K and 5V gives a range of 0 to 200 Lux, but can be over 700 Lux with a 1K resistor). The internal dark current cancellation enables high accuracy over the full temperature range, even at low light levels.
Features:
· Integrated high gain photo-current amplifier
· Dark-current cancellation
