Hi can u give details about "Design and Implementation of a Socket with Low Standby power"

This socket supplies the appliances with power when the user turns them on. When the user turns them off,this socket shuts the electric power off and reduces the standby power to zero.This can be a solution to electric home appliances
drawing standby power when they are plugged in.The design uses an MCU which receives signals from a PIR sensor which detects the user when approaching the socket and the appliances. A power detector provides an MCU to control the
SSR On/Off when used as an appliance switch for shutting off the standby power.The components used dissipate very little power. The MCU monitoring program provides both automatic detection of the user by the PIR sensor and detection of power consumption.
When the user is detected by the PIR sensor , the power for the electric home appliances is enabled. Conversely, if the PIR sensor doesnâ„¢t detect the user,
the power is cut off as the appliances were unplugged. If the appliances are working but the user leaves, the power continues to come from the socket until the work is finished. Because of this requirement there is the the power detector circuit.A microcontroller unit (MCU) controls the solid state relay (SSR) to supply the power for electric home appliances.
Power detector ckt:
we use the toroidal coil inductor as a current sensor that detects whether the appliance is working. When an AC current passes through an inductor, a small
sinusoidal voltage is induced.This small voltage is amplified and converted into a DC signal by the diodes and capacitors and is then given to a comparator, compared with the predefined voltage value to determine whether the appliance is in the work state or not.
This design design requires 5 V DC from the AC/DC converter as the working voltage.the power detector circuit and the MCU are integrated in a board, and other circuits are connected to the board.
