EDA sensor

Postby Bitclem » Mon Feb 06, 2017 6:35 pm

I recently purchased bitalino plugged kit and I'm working with the EDA sensor to some applications. A regard I would like to ask some questions:
- how can I get the sequence of EDA values ​​represented on the graphic even on a counter with a digital display? What should be its characteristics and how to mount it? Can I buy it on bitalino store?
- How can I get a graphical representation of bar (vertical and horizontal) of the EDA values?
- I would like to trigger different alerts (eg. Sound and light) to values ​​other than as predetermined threshold. Example: activation of a buzzer for higher values ​​and equal to that threshold - light activation of an LED for EDA values ​​lower than that set for the threshold. Where and how can I install them?
Many thanks and best regards

Hi there,

Thank you for your preference for BITalino parts... please find our comments and suggestions bellow; if you have further questions let us know:

- How can I get the sequence of EDA values ​​represented on the graphic even on a counter with a digital display?
The EDA has an analog output pin... you can connect it to any device with an ADC, MCU and eventually a display.

- What should be its characteristics and how to mount it?
Examples include the Arduino and Raspberry Pi; note that the recommended setting is to have the whole assembly battery powered.

The pinout of the EDA sensor is available here: http://bitalino.com/datasheets/REVOLUTION_EDA_Sensor_Datasheet.pdf

You can see an example setup schematics from the ECG sensor here: http://forum.bitalino.com/viewtopic.php?t=98#p279

- Can I buy it on bitalino store?
Currently on the BITalino store we only have the components for real-time data acquisition and transmission:

- How can I get a graphical representation of bar (vertical and horizontal) of the EDA values?
You could use for example an Arduino Pro Mini with a LED bargraph:

- I would like to trigger different alerts (eg. Sound and light) to values ​​other than as predetermined threshold. Example: activation of a buzzer for higher values ​​and equal to that threshold - light activation of an LED for EDA values ​​lower than that set for the threshold. Where and how can I install them?
On the sensor directly it may not be easy. Using the BITalino Core you can use the digital output ports, and using the Arduino or Raspberry Pi you can use the available digital pins.

Best regards,
The BITalino Team
