When the sound exceeds the set threshold, the relay automatically pulls in and delays disconnection. The light control function can be turned on or off. A control device with a certain sound intensity/light intensity after turning on. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 x Sound Sensor Light Sensor Control 1. Versatile Control Options: The sound sensor light sensor control allows for flexible usage, enabling either sound control alone or a combination of sound and light control. Note that light control cannot be used independently. 2. Adjustable Sound Amplification: Featuring a two-stage sound amplification system, the delay switch can amplify sound by 100 to 5000 times, corresponding to approximately 10 to 90 decibels. The sound intensity threshold is adjustable to suit various environments. 3. Customizable Light Sensitivity: The relay module offers adjustable sensitivity from 10 to 10000LX, covering a range from complete darkness to bright midday sunlight in the shade, allowing precise control based on ambient light conditions. 4. Adjustable Delay Time: The delay turn off switch provides an adjustable delay time ranging from 3 to 60 seconds. This non-precision delay is related to the capacitor's charge and discharge, as well as sound triggers, offering tailored timing for different applications. 5. Reverse Polarity Protection: The relay board includes reverse polarity protection, ensuring that incorrect power connections will not damage the module, providing enhanced durability and reliability in various setups.
