Muscle Sensor Board for Electromyography Inputs Description This compact electromyography (EMG) sensor board measures the electrical activity of voluntary muscles, filters and rectifies the signal, and provides a usable voltage output proportional to muscle activity. It is designed for wearable, interactive projects where muscle contractions are used as control inputs. Key benefits Turn muscle activity into control signals: read a voltage that varies from 0 to the supply voltage as a muscle contracts, enabling direct control of electronics without conventional switches. Simple to use: attach standard surface electrodes, read the output, and map muscle contractions to your device inputs. Flexible power and outputs: works from 3.1 V to 5 V single supply, and includes both processed and RAW outputs for advanced signal processing. Wearable and tidy: the updated form factor supports direct connection of sensor leads and reduces bulky cabling for wearable applications. Main features Measures and conditions EMG signals using onboard filtering and rectification. Output voltage scales from 0 to Vcc depending on muscle activity. RAW output available for access to unprocessed signal data. Single supply operation from 3.1 V to 5 V. Clear power supply polarity pins. Status LED indicators and an On/Off switch for easy operation. Wearablefriendly board design that supports direct electrode lead attachment. Optional shielded cable and power supply accessories to improve signal integrity and versatility. Electrodes are not included. Compatibility and connectivity Compatible with standard surface EMG electrodes and leads. Outputs are analog voltages suitable for microcontrollers, ADCs, data acquisition devices, and motor or actuator controllers when used with appropriate interface electronics. Works with a wide range of prototyping and embedded systems that accept 0 to supply voltage analog inputs. Typical applications Gesture and musclebased user interfaces for robotics and wearable controllers. Game and assistive input prototypes where muscle activity replaces or augments buttons, levers, or joysticks. Interactive art, music controllers, and experimental input devices where intuitive, bodydriven control is desired. How to get started 1. Attach standard surface electrodes to the target muscle area (electrodes not included). 2. Connect electrode leads to the sensor board and power the board with 3.1 V to 5 V. 3. Read the processed output for a clean control signal or the RAW output for custom signal processing. 4. Map the voltage output to your application logic or control hardware. What is included EMG sensor board with onboard filtering, RAW output, LED indicator, and on/off switch. Note: surface electrodes and any optional shielded cables or power accessories are not included. Safety and usage notes Intended for research, prototyping, and hobbyist projects as an interface device. Do not make medical, therapeutic, or diagnostic claims. Use standard safe practices when placing surface electrodes on skin and follow the electrode manufacturer instructions. This sensor board provides a straightforward way to convert muscle electrical activity into analog control signals, with flexible power options and outputs suitable for a wide range of interactive and wearable projects.
