Abstract
In order to test the illuminance indoor, we use 16-bit MCU msp430f449, silicon photo cell BPW34 and clock chip DS12C887 to design an indoor illuminance test system with calendar function. Voltage signal is collected by BPW34, and it goes through the amplifier to be enlarged. Then it is transferred to the 12 bit AD of MSP430. Finally the outputs are displayed in the LCD display module. The clock chip DS12C887 controls the real-time display, which can be modified through the buttons. Illuminance measuring range is 0.5lx-2000lx and the accuracy is 0.5lx.
