51 smart trash can design-infrared obstacle avoidance-toggle-relay-infrared pair tube-wt588d-photosensitive-LED

This design consists of STC89C52 single-chip circuit + toggle switch circuit + infrared obstacle avoidance sensor + relay circuit + infrared pair tube circuit + WT588D voice module circuit + photoresistor circuit + LED lamp circuit + power supply circuit.

1. Select the working mode by flipping the switch. Turn the toggle switch 1 up to the automatic mode, and down to the manual mode.

2. Manual mode: Turn the toggle switch 2 up, the relay is closed, dial down, and the relay opens.

3. Automatic mode: the obstacle avoidance infrared sensor detects the obstacle, the relay closes, the obstacle avoidance infrared sensor detects the obstacle 1 does not detect the obstacle, the relay opens.

4. If the infrared pair tube detects an obstacle, the voice module WT588D will prompt the trash can to be full. Otherwise, the voice module does not broadcast any information.

5. The light is off during the day, and the light is on at night.
