The digital illuminometer is composed of an integrated light sensor (ISL29035), OLED display and a cap-touch keypad. It can be used to monitor the lux value of a variety of lighting conditions. The OLED display method can be controlled with the touch key input, while the LED brightness also can be changed as a function of ambient light changes.
Optimized for handheld applications, this design incorporates the RA2A1 microcontroller, which with its analog support, can simply implement USB charging of a Li-ion battery. Voltage and current can be monitored and controlled with real-time feedback, while charging mode can be adjusted as required.
