Description: This muscle sensor from Advancer Technologies measures a muscle’s activity by monitoring the electric potential generated by muscle cells. This is referred to as electromyography (EMG). The sensor amplifies and processes the complex electrical activity of a muscle and converts it into a simple analog signal that can easily be read by any microcontroller with an analog-to-digital converter (ADC), such as an A-Star or Arduino – or even a Maestro servo controller. As the target muscle group flexes, the sensor’s output voltage increases. The exact relationship between the output voltage and the muscle activity can be fine-tuned using an on-board gain potentiometer.
A cable is included for connecting three electrodes to the muscle sensor board. One end of the cable is terminated with a single 3.5 mm audio-style connector that can be plugged directly into the board. The opposite end has three snap-style connectors to make it easy to attach and detach electrodes.
- Analog voltage output from 0 V to +Vs (supply voltage)
- 1″×1″ (1.13″×1″ including audio-style jack)
- Adjustable gain
- Typical operating voltage of ±5 V
- Breadboard compatible
- 3.5 mm audio-style plug for easy connection
