Abstract
An induction trash can circuit includes an active infrared sensor, a microcontroller, a driving circuit and a motor for controlling the opening and closing of a lid. The power-saving method is achieved through the following steps: in a standby state, the microcontroller controls the active infrared sensor to emit an infrared pulse signal to an induction area; if no obstacle exit in the induction area, the active infrared sensor outputs no signals, the program of the microcontroller immediately enters a sleep state; after the program of the microcontroller sleeps for a period of time, a watchdog timer in the microcontroller wakes up the microcomputer controller to make the microcontroller re-enter a working state; and if the microcontroller is in a standby state, the above process is repeated.
