Grove – LM358 Amplifier Sound Sensor – Seeed Studio
The Grove – LM358 Amplifier Sound Sensor is a reliable and sensitive audio detection module designed to measure environmental sound intensity with precision. Built around the LM358 operational amplifier and an electret microphone, it provides a clean analog output that can be easily sampled by microcontrollers such as Arduino, Raspberry Pi and Seeeduino. Operating across a wide voltage range of 4–12 V, this sensor delivers stable performance even under varying conditions, thanks to the LM358’s dual-channel, low-offset and wide-temperature operational capability. With its Grove unified socket, the module supports effortless plug-and-play integration, making it ideal for sound-triggered applications, noise monitoring, interactive devices and smart home systems. Whether you are building a sound-activated lamp or developing audio-responsive projects, this module offers dependable amplification and consistent detection accuracy.
