The Gravity: Analog EMG Sensor by OYMotion is a high-quality, non-invasive sensor designed to detect sEMG (surface electromyography) signals, reflecting human muscle and neural activity. This sensor is a perfect solution for projects requiring real-time muscle activity monitoring, such as human-computer interactions, robotic control, and biofeedback systems.

The module features a differential input and built-in analog filter circuit, which amplifies weak muscle signals (±1.5mV) by 1000 times while minimizing noise interference. The output signal range is 0 to 3.0V, with a 1.5V reference voltage. It provides easy-to-use, high-quality signal collection without the need for conductive gel, making it more convenient and durable than traditional medical electrodes.

Key Features

  • Metal dry electrodes for long life and easy usage

  • Differential input with high common mode rejection ratio (CMRR)

  • Low power consumption with single 3.3V to 5.5V power supply

  • Provides accurate readings of muscle strength and activity

  • No conductive gel needed, making it more convenient and durable

  • Can be easily integrated with Arduino for muscle activity detection and robotic control

Applications

  • Human-computer interaction for assistive technology

  • Robotic control using muscle signals

  • Biofeedback systems for physical therapy

  • Interactive projects such as myoelectric mouse and wearable devices
