Resistance between two capacitive sensors

Using Arduino Project Guidance
#1

Seeduino Lotus
Mini Breadboard
Grove Touch sensor (2x)

Dear,
For a project I want to create a product, that is activated when two different persons both touch a different touch sensor. The product should not be activated when one person touches the two sensors. So, I want to research if both situations create a different input. I want to do this with a “resistance measurement” between the two sensors.

  • If one person touches both sensors, the resistance is lower than if it were two different persons (unless the two persons touch each other).
    To simulate this I first used the Seeeduino Lotus and two Grove touch sensors. But the Grove Touch Sensors do not provide an analog signal. So, I have to create the sensors and build the circuit myself. I do have a mini bread board, but minimal knowledge...
    Do you have advice how to approach this research?
    Thank you in advance!

I think you may have problems in getting this working , worth a try with two , but it might stop the capacitive action working as you will end uk with both sides of the sensor connecting to the Arduino .
Try it !

The option is to use two switches some distance from each other so one person can’t reach both !

Hi,
Welcome to the forum.

Please read the post at the start of any forum , entitled “How to use this Forum”.

As these are capacitive and not resistive you may have chosen the wrong sensor.

Can you please tell us your electronics, programming, arduino, hardware experience?

Thanks… Tom… :slight_smile:
