Feature: 1. After the module is triggered by the sound, there is output, the output automatically turns off after 10 seconds delay. 2. High-power transistor output can directly drive the motor or high-power LED, the maximum current carrying capacity of 1.5A. 3. Wide supply voltage 3-9V, can be powered by two dry batteries or 5V power bank. 4. Built-in anti-interference circuit, will not misoperate due to the interference of motor and (except noise). 5. Can complete works such as: voice control light, voice control fan, voice control car, etc. Specification: Item Type: Voice Control Delay Switch Working Voltage: DC 3-9V Drive Current: 1.5A Package List: 1 x Voice Control Delay Switch
