sound trigger

sound trigger



The sound trigger listens to the noise level in your room, and sends an ON signal when it gets over a certain level. You can make that threshold louder or softer using the included screwdriver. We like to use it with an LED to light up your room when you snap your fingers.

The sound trigger features an electret microphone that triggers a 5V output when the set threshold is reached. The output of the module will remain high for 3 seconds. If the input signal is high, the module functionality is enabled. If the input signal is low, the module function is disabled.
