This ambient light sensor carries the TEMT6000 phototransistor. The phototransistor is connected to a pull-down resistor to form a voltage divider that produces an analog voltage output between 0V and +5V as a function of the light detected in the visible spectrum. Lower output voltage is an indication of less light detected.
The LED current-limiting resistor is set to deliver approximately 20mA. The current requirement can be met by some microcontroller I/O lines, allowing the sensor to be powered up and down through an I/O line to conserve power.

Code: MR003-007.1This reflectance sensor can be used for edge detection systems and for making line following robots.
Code: MR003-004.2GP2Y0D810Z0F is a distance measuring unit. The output voltage stays low in case an object exists in the specified distance range, so this sensor can also be used as proximity sensor.
