ACEBOTT Analog Sound Sensor Easy-Plug for ESP32/Arduino

High-Sensitivity Electret Condenser Transducer: Captures ambient acoustic wave fluctuations and converts sound pressure changes into continuous electrical signals.

Easy-Plug RJ11 Cable Interface: Outfitted with an integrated RJ11 modular connector port that eliminates wiring errors and enables instant plug-and-play setup with ACEBOTT expansion shields.

Continuous Analog Voltage Output: Generates a real-time analog voltage signal directly proportional to room noise levels and voice intensity for microcontroller ADC logging.

Onboard Signal Pre-Amplification: Features built-in active operational amplifier circuitry to boost weak audio signals, delivering clean and reliable telemetry to host controllers.

Dual ESP32 & Arduino Hardware Compatibility: Fully integrated for seamless operation on 3.3V and 5.0V logic levels across ESP32, Arduino, and STEM learning platforms.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with a top-mounted electret microphone capsule, black plastic RJ11 connector housing, and gold-plated contacts.

Technical Specifications:

Operating Voltage: 3.3V - 5.0V DC.

Interface Type: Easy-Plug RJ11 Modular Cable / Pin-Header Compatible.

Output Signal: Analog Voltage.

Color: Black PCB with White Easy-Plug Port and Silver Microphone Capsule.

Usage Advice: Connect using an Easy-Plug RJ11 cable to an ACEBOTT shield or jumper to an analog ADC input pin; position the open face of the electret capsule toward the primary audio source.

Maintenance: Keep the microphone inlet free from dust, debris, and moisture; clean board surfaces gently using a dry, soft microfiber cloth.

Essential STEM Audio Module: Position as a beginner-friendly acoustic transducer for classroom robotics, smart voice-activated light triggers, decibel monitoring stations, and interactive sound displays.

Highlight Solderless Easy-Plug Convenience: Emphasize how the RJ11 modular connection streamlines hands-on learning by eliminating breadboards and complex jumper wire clutter for students and educators.
