Sound-controlled LED circuit board, solar induction switch for low-voltage lighting

Welcome to our shop! Discover our sound and light control module, a versatile and easy-to-use printed circuit board (PCB) for your automated lighting projects. This smart module combines sound detection and ambient light control for efficient automation. Photoresistor Functionality: Equipped with a photoresistor, the module disables voice control in the presence of ambient light. It only becomes operational in a dark environment, thus saving energy during the day. 24/7 Control: For continuous operation day and night, simply cover the photoresistor with an opaque object (such as black electrical tape). This disables the light detection function. Input and Output Voltage: It operates over a wide DC voltage range of 3V to 30V. This compatibility makes it perfect for use with solar panels or other alternative power sources for your DIY voice-controlled lighting projects. Applications: This sound and light switch panel is ideal for a variety of applications, including solar lights, DC-powered hallway lights, garage lights, and much more. Easy Installation: The module comes with power cables for both input and output, eliminating the need for additional wiring and simplifying installation. Detailed Specifications: - Item Type: Voice-Controlled Light Circuit Board - Material: PCB - Input Voltage: DC 3V-30V (Do not use with dry cell batteries) - Output Voltage: DC 3V-30V (same as input voltage) - Maximum Output Lamp Wattage: The maximum supported wattage is equal to the supply voltage multiplied by 4 (e.g., 12V supply = max 48W lamp). The current must not exceed 4A. - Audible trigger threshold: Approximately 20 decibels (effective detection within 1 meter) - On/Off delay: Fixed at 45 seconds (non-adjustable) - Light control function: As described, voice control is disabled in the light. Cover the photoresistor for continuous control. Package contents: 1 x Circuit board, 1 x Instruction manual in English
