Name: DC3-30V sound and light control switch module
Note: Then the LED and polarity non-incandescent lamp, please be sure to see the main picture of the second, the output red wire is negative, white wire is positive, remember! Remember! Remember!
Can enter the voltage DC3-30V (recommended control between 3.7-24V, can not directly 220V high voltage)
The output voltage is the same as the input voltage. The current rating is 1A. As long as it is within the required range, you can connect any product you want to control, such as solar light, small motor, alarm and so on.
With a photosensitive resistor, a bright ambient sound control is invalid, no light can be controlled. Remove the photoresistor, you can control the whole day.
