ECG, EMG, GSR, Resp and accelerometer recorder

Fig. PCB visualisation.

Measurement channels:
- ECG - 2 channels at 24-bit resolution and a sampling rate of 500 Hz, 1 kHz or 2 kHz
- EMG - 1 channel at 24-bit resolution and a sampling rate of 500 Hz, 1 kHz or 2 kHz
- GSR - bioimpedance - 1 channel, 16 bits, 100 Hz
- RSP - respiration curve - 1 channel, 16 bits, 100 Hz
- Gx, Gy, Gz - acceleration in 3 axes - 3 channels, 16 bits, 100 Hz
- BATT - battery discharge level - 1 channel, 8 bits, sampling rate 1 Hz
Measurement data is sent to the managing system over a BlueTooth link. Two AA (LR6) batteries are used for the power supply.

Fig. The control application.

The application managing the acquisition module requires a computer with a BlueTooth module and at least Windows 7.
