According to development direction and users’ demand of smart home

a smart lighting switch system based on Zig Bee technology is designed. Design scheme adopts a new generation of SOC chip CC2530 used in the wireless receiver and transmitter module

and it makes the module has the functions of low cost

low power dissipation

high reliability

Ad Hoc network

horizon communication. At the same time

the ARM7 embedded processor LPC2132 is used as the system’s microcontroller module

owing to it

the design is simpler and more reliable

and it let the system has the ability of distributed processing. After measuring the zero crossing point of city power

the delay timer is set

and the turn-on time of TRIAC can achieve the aim of light control. The results indicate that

this design let the home lighting system be more controllability

save more energy

make the home environment more comfortable.
