Taidacent 12V Sound Sensor Module Sound Delay Computer Audio Signal Input Control Switch Stable Performance Corridor Delay Switch

Functional Description: The module detects that there is an audio signal relay turned on, no audio signal is delayed, and the audio trigger signal is continuously received within the delay time. The relay is always on, the relay will not be disconnected and flashed, and the audio trigger signal will stop. After that, the timing starts from the new time, and the delay time reaches the relay disconnection; Features: 1, using single-chip control, stable performance; 2. This module is triggered by the audio signal. When the audio 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> 3. The module detects that the audio signal relay is turned on, there is no audio signal, the delay is disconnected, the audio signal is continuously received during the delay time, the relay is always on, the relay will not be disconnected and flashed, the audio trigger signal After stopping, the timing starts from the new time, and the delay time reaches the relay disconnection; 4, there is timing potentiometer adjustment time, product design is adjustable from 1 to 180 seconds, can also be customized time range; 5, timing time error is 5% 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;
