Gravity: Analog EMG Sensor by OYMotion
385 units available with a short lead time.
The Gravity Analog EMG Sensor by OYMotion detects surface electromyography (sEMG) signals to measure muscle and neural activity. The sensor amplifies the tiny sEMG signal (±1.5 mV) by 1000× and filters noise through differential input and analogue filtering, outputting a clean 0–3.0V analogue signal with 1.5V reference voltage.
The module uses reusable metal dry electrodes — no conductive gel required — making it convenient for repeated use in both static and dynamic applications. Connect to an Arduino or other microcontroller to detect muscle tension, measure contraction strength, and analyse sEMG waveforms.
