New Smart Electronics Muscle Signal EMG Sensor Module
Introduction:
Through the potential measurement of muscle active state, referred to as EMG (EMG), has always been used for medical research and neurological - muscle disease diagnosis. However, with the advent of microprocessors and integrated circuits that are more powerful, EMG circuits and sensors have been installed in prostheses, robotic technology, and other control systems.
Feature:
1. Size: 25.4mm * 25.4MM
2. Easy to use, specially designed to use the microcontroller
3. Adjustable gain
4. The pin design conforms to the breadboard
Parameter:
1. Operating voltage: ± 5V
2. Gain setting: 50 kΩ
3. Signal amplification chip: AD8221
4. Output signal: 0 ~ + Vs (output signal, after rectification and smoothing)
5. Differential signal input: 2-5mV
Hardware connection:
Materials to be prepared:
1.Ard development board one
2. A piece of muscle sensor module
3. One of the electrodes is connected
4. Electrode 3
5.9V battery 2
6. male and female DuPont pin 5
7.USB serial line one
Hardware wiring steps in detail
1, connect the muscle sensor module power supply (two 9v battery)
A. Connect the positive terminal of the first 9v battery to the + Vs pin of the muscle sensor module.
B. Connect the negative terminal of the first 9v battery to the positive terminal of the second 9v battery and connect it to the GND pin of the muscle sensor module as shown in the figure above.
C. Connect the negative terminal of the second 9v battery to the -Vs pin on the muscle sensor module.
2, connect the three measurement electrodes, as shown above
A. Determine which muscle tissue you want to detect (such as biceps, forearm, calf), thoroughly clean that part of the skin.
B. Place an electrode piece in the center of the muscle to be tested and connect the first electrode tab to the green cable connector.
C. Then place the second electrode piece at the end of the muscle to be detected above, and then connect the second electrode piece to the red cable connector.
D. Continue to place the third electrode piece to the bone position next to the detection muscle, or elsewhere in the absence of muscle, and then connect the third electrode piece to the yellow cable connector.
3, connected to the main control board (such as: Ardu uno)
A. Connect the SIG pin of the muscle sensor module to the analog pin A0 (or other analog pin) on Ardu with the DuPont line.
B. Connect the GND pin of the muscle sensor module to the GND pin on Ardu with the DuPont cable.
