QINIZX 2PCS DC 3V 15V 5V 12V Voice Control Delay Switch Miniature Microphone Sound Activated Time Turn Off Module Alarm Sensor for LED Relay Electronic Device

Voltage Range: DC 3V-15V, low power cOnsumption, 0.1mA ultra-low standby current, Maximum output current of 1.5A, Mini module size 1.14x0.43inch(LxW). With LED indicator, Led On when the output, and when the output is off, the LED light is off. Voice-activated delay switch module, voice control sensitivity is adjustable, delay Time is adjustable. Sound control sensitivity adjustment: Rotate the adjustable potentiometer to change the size of the trigger sound. Rotate counterclockwise for low sensitivity (it requires a large sound module to be triggered), and rotate clockwise for high sensitivity (small sound module will be triggered), freely adjust the sensitivity. Delay Time Range: Default 0-25 seconds to adjust arbitrarily, if you need a longer delay, you can increase the capacitance value (customers can freely adjust the delay output time, counterclockwise rotation is short delay time, clockwise rotation is Long delay time). Working Status: Delay time-when there is a sound trigger, the output will start immediately, and the output will be turned off when the delay time is reached. For example, if a 1-minute delay is set, the OUT will start to output immediately when there is a sound. The delay time will not accumulate if there is another sound within 1 minute. When the delay reaches 1 minute, the output will be turned off. At this time, there will be another sound and start a delay cycle. Note: This module is not suitable for controlling devices that make sounds by themselves, such as motors, buzzers, etc. Suitable for controlling silent equipment such as LED.
