Ambient light sensor circuitry includes a photodetector, a controllable current source, and control circuitry. The photodetector is coupled between a supply voltage and an intermediate node and configured to provide a photodetector current proportional to an amount of light detected thereby to the ...
At the heart of an energy-harvesting system is the ability to measure ambient light accurately. This design idea describes a simple, cost-effective circuit that provides a voltage proportional to the intensity of ambient light. The sensor is a light-dependent resistor (LDR)—photoresistor Model ...
