1.2. Typical Unfiltered Sensor Output Figure 2 shows a typical unfiltered EDA sensor output acquired while being in a relaxed state. The raw digital sensor values received from the BITalino device ranged between 0 and 2 -1 (n=sampling resolution) were converted into the original unit of measurement of this sensor (µ) using the transfer function found in section Transfer Function (Conversion Formula).
> Psychophysiology > Relaxation biofeedback 1.6. Transfer Function (Conversion Formula) The analog sensor signals acquired with BITalino devices are converted into digital values ranged between 0 and 2 -1 (n=sampling resolution, usually 6-bit or 10-bit) and streamed in the raw digital format.
Electrodermal Activity (EDA) User Manual 1.7. Electrode Connections & Sleeve Color Meanings The BITalino EDA sensor can be connected to electrode cables and open wire cables with different connection types, see Table 1. Table 1: Possible connection types for the EDA sensor...
Electrodermal Activity (EDA) User Manual 1.8. Physical Characteristics The BITalino EDA sensor comes in a size of 12mm x 27mm (see Fig. 4). Figure 3: Physical characteristics of the standard EDA sensor. 7 of 18...
Electrodermal Activity (EDA) User Manual 2. Application Notes BITalino EDA sensor is designed to acquire the change of skin activity such as sweat with two measuring electrodes. One example is the placement of the electrodes on the anterior side of the hand on two adjacent fingers of interest (see Fig.
3.1.1. BITalino (r)evolution Board The BITalino EDA sensor comes already connected to the BITalino (r)evolution Board. Figure 6: EDA compatible BITalino (r)evolution Board pre-connected to an EMG sensor with UC_E6 connector on one side. 3.1.2. BITalino (r)evolution Plugged The BITalino EMG sensor (UC-E6 sockets) is compatible with all 6 analog input channels of the BITalino (r)evolution Plugged with a sensor cable with UC-E6 connectors.
The BITalino EDA sensor (no connections or Molex Sherlock plugs) is compatible with the BITalino (r)evolution Freestyle. Figure 8: BITalino (r)evolution Freestyle with the possible connection ports (marked in green) for the EDA sensor (without connections) using the Molex Sherlock plugs and sockets or self-mounted cables.
3.2. Configuring the Sensor in OpenSignals 3.2.1. OpenSignals (r)evolution (Windows, macOS, Linux) Open the OpenSignals (r)evolution device manager to access and configure your BITalino device. Figure 10: Access the OpenSignals (r)evolution device manager. Select the device you intend to use for acquisition by clicking on ENABLE button on the device panel in the OpenSignals device manager.
