- Reference: R-9257 · EAN: 5945025479347

Kit for measuring electrical muscle activity, useful in biofeedback projects and EMG analysis with Arduino or other development boards. Includes the module and 3 self-adhesive gel pads and wires, offers 0V to Vs analog output for easy reading, mounts quickly on the breadboard, works with dual power supply between plus minus 3.5 and plus minus 9VDC.
The EMG sensor module is a product designed to measure the electrical activity of muscles through surface electromyography (sEMG).
Based on the TL084 quad operational amplifier with JFET input, the module offers a very high input impedance, low noise, and a slew rate of 16 V/µs, ensuring faithful acquisition of the muscle signal.
