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

Features

• Voltage range: DC 3V-15V, low power consumption, 0.1mA ultra-low standby current, Maximum output current of 1.5A, Mini module size 1.14×0.43inch(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.
