Taidacent 12V VoiceActivated Delay Switch Sound Detection Relay Module Sound Sensor Module Voice Alarm

The module detects that there is a sound relay connected, no sound is delayed, and the sound trigger signal is continuously received within the delay time. The relay is always on, the relay will not be disconnected and flashed, and after the sound trigger signal is stopped, Start timing from the new time, the delay time is up to the relay disconnected; Product features: 1, using single-chip control, stable performance; 2, with anti-power reverse protection diode, effectively protect the product; 3, with a large current regulator tube to provide sufficient power; 4, the output can be connected to AC 250V 10A or DC 30V 10A load; 5. This module is triggered by the sound signal. When the sound signal reaches a certain value, it will instantly close, the module will start timing, the green LED will be illuminated, the relay will be closed, the timing will be finished, the green LED will be off, the relay will be released, and the relay will be restored to the normally closed end; Br> 6. The module detects that there is a sound trigger signal relay is turned on, there is no sound trigger signal, the delay is turned off, the sound signal is continuously received within the delay time, the relay is always on, the relay will not be disconnected and flashed, the sound After the trigger signal stops, the timing starts from the new time, and the delay time reaches the relay disconnection; 7, with timing potentiometer adjustment time, product design is adjustable from 1 to 180 seconds, can also be customized time range; 8, the timing time error is 5% Product application: 1, with other various sensors plus relay module, you can do a variety of delay switches, directly with AC 220V products; 2, corridor delay switch, delay energy-saving products;
