Kitronik USB LED Strip with Light Sensor
The Kitronik LED strip with a sensor has been specifically designed for use in custom enclosures for low-power lighting. The onboard sensor makes it the perfect choice for a night light or desk illumination that comes on when the ambient light levels drop. If desired, the sensor can be bypassed with a flick of a switch for continuous lighting.
The power requirements of the board fall within the supply rating of a computer USB port (under 100mA). The PCB is approx. 50mm long, 10mm wide and has a mounting hole at one end. The board features 5 bright LEDs (Luminous Intensity ~8000mCd), a micro-USB power input, a phototransistor, and a three-way switch. The board also features GND and +5V pads for attaching alternative power sources.
The side-mounted slide switch has three positions: On, Off and Sense. The On and Off positions directly turn on/off the LEDs, whereas the Sense position makes use of the end-mounted phototransistor to turn the LEDs on when the darkness threshold has been reached.
A clear gap has been left between the phototransistor and the rest of the components to allow a barrier to be placed between them in an enclosure design, ensuring no light from the LEDs can affect the sensor.
Features:
