51 infrared control trash can design-infrared obstacle avoidance-infrared pair tube-voice-RELAY

This design is composed of STC89C52 single-chip circuit + infrared obstacle avoidance sensor circuit + infrared pair tube circuit + voice module circuit + relay module circuit + power supply circuit.

1. If the infrared obstacle avoidance sensor detects an obstacle, the relay is closed, otherwise, the relay is disconnected. (The relay is connected to the electromagnetic lock)

2. If the infrared pair tube detects that the garbage is full, the voice loop alarm: the garbage is full, please replace it as soon as possible (voice messages can be recorded by yourself). Otherwise, no alarm is issued.
