The TekBud Sound Sensor Module (LM393) is a compact, sensitive sound sensor module designed for audio detection in electronics and automation projects. It’s ideal for use in Arduino-based setups, Raspberry Pi, robotics, and other DIY systems that need to respond to sound stimuli.
Using the LM393 comparator chip, the module detects sound levels and outputs a digital signal. When sound is detected, the output pin goes LOW and the onboard signal LED lights up, allowing for easy testing and response configuration.
This sound sensor for Arduino is perfect for building audio-reactive systems, such as sound-controlled lighting, alarms, and clap-switches. It operates on 4V to 6V DC, with low power consumption, and comes with a simple 3-pin interface—VCC, GND, and OUT—for fast and easy integration.
Whether you're a hobbyist, student, or robotics enthusiast, the TekBud LM393 sound module is a reliable, cost-effective tool for bringing interactivity to your electronics projects.
