The MyoWare Muscle Sensor is an all-in-one electromyography (EMG) sensor that measures the filtered and rectified electrical activity of a muscle. It outputs 0 V to Vs (supply voltage) depending on the level of activity in the selected muscle, making it straightforward to read with any analogue input.

Powered from a single 3.3 V to 5 V supply, the MyoWare connects directly to development boards without requiring dual-polarity power. Electrodes snap directly onto the board, eliminating the need for separate cables and making the sensor wearable.

Key Features

• Single Supply Operation – Runs from 3.3 V to 5 V, no dual-polarity supply needed
• Embedded Electrode Connectors – Electrodes snap directly onto the board for cable-free, wearable use
• Dual Output – Filtered/rectified EMG envelope output plus a raw EMG waveform output
• Polarity-Protected Power Pins – Prevents damage if power is accidentally connected in reverse
• On-Board Power Switch – Easily test power connections before use
• LED Indicators – Power indicator LED and a muscle activity LED that brightens with flexion
