Hi all,

I am making a sensor that will cause an increase in voltage (or current) when it encounters certain chemicals. And, I am interested in plotting a graph of voltage versus time. The graph would show a horizontal line without chemicals excitation but when the sensor is excited by certain chemicals, it will cause a "peak" in the graph. And when the chemical is removed, the graph goes back to be horizontal.

I am planning to use ADC-11/10 and PicoLog for this purpose. Is it suitable? And how should i set the PicoLog?

Thank you.

Regards,
William

Hi and thank you for your post.

This depends on what kind of sampling rate you are looking for and what kind of voltages you are going to be measuring.

Kind regards

Ziko
