FAQ

What are configurable mechanical components?

Configurable components are products in which you can select specific design features, and see the price and delivery times at a glance.

The most used configurators include linear shafts, linear guides, miniature linear guides, aluminum extrusions and aluminum sheets. Select your specifications from material, surface treatment, length and diameter.

Description
This module allows you to detect when sound has exceeded a selected set point. The sound is detected via an electret condenser microphone and fed into an LM393 operational amplifier. The sound level setpoint is adjusted via an on-board potentiometer in a more sensitive clockwise direction and a less sensitive counterclockwise direction. When the sound level exceeds the set point, an LED on the module illuminates and the output is sent low. Since this device measures whether or not the sound has exceeded a threshold, you're basically left to decide what you want to do - you can do something when it's quiet and/or you can do something when it's loud.
