Dry Electrode Myoelectric Muscle Sensor Module
This Dry Electrode Myoelectric Muscle Sensor Module is a compact, ready-to-use electromyography (EMG) sensor designed for non-invasive muscle activity detection. Featuring a built-in amplifier and filter circuit, it captures the muscle’s electrical signals (up to ±1.5mV), suppresses noise, and provides a clean analog voltage output (0–3V), ideal for microcontroller-based projects.
Features
- Utilizes a dry electrode design—no need for conductive gels—ensuring ease of use and long service life.
- Built-in differential amplifier and analog filter enhance sensitivity and remove interference.
- Detects faint EMG signals (±1.5mV) and outputs analog voltage relative to muscle activity (0–3V).
- Operates on a single supply voltage (3.3V to 5.5V), facilitating compatibility with most microcontrollers.
- Low power consumption and compact size enable seamless wearable integration and mobile use.
- Equipped with standard connectors and straightforward analog output for easy interfacing with ADC inputs.
