GamlReid DC5V 12V 24V Sound Sensor Light Control Relay Switch Time Delay Turn Off Module

Product description Our latest! Sound and light control / relay switch of voice module, all the network the single sound sensitivity / sensitivity intensity / adjustable delay 1-60 S total performance of the whole, super stable! Note: baby plate with red and green, we do not accept the choice, random delivery. The module uses: The ambient sound and the light intensity automatically detect when a sound exceeds the set limit, the relay is energized and the time delay period automatically, and then turn off. Light control function can be activated also be closed. The control apparatus for a certain intensity of light or intensity of light or less open. Microphone image and welding by photosensitive resistor only for demonstration purposes, in order to avoid the interference of the relay off microphone sound, the effective delivery of products with an extension cable. Module Features: 1. Voice / sound and light control Optional: You can only use the voice, sound and light control function can also be used at the same time. 2. The two sound amplification, 100-5000 adjustable amplification, (corresponding to about 10 to 90 decibels of sound), adjustable sound intensity threshold. 3. The intensity of light threshold 10-10000LX adjustable sensitivity (more or less equivalent to full black for the sunny half-day shadow of brightness range) 4. Pull 1-60 S adjustable delay time (for non-precision delay, capacitor loading and unloading delay time, with sound triggering a relationship). 5.Reverse polarity protection, reverse of the power supply does not work, will not burn the module. 6. Wide input voltage 5-30 V, ultra-wide scope. Module parameters: Supply voltage: 5-30 V (<6 V> Turn off the power supply when 6Vd shorting cap, remember! The wrong choice can burn the module) Range of sound intensity: about 10-90 dB adjustable.
