Touch Sensor

touch sensor

Overview

This breakout board is the simplest way to create a project with a single “momentary” touch sensor. When a capacitive load is detected (e.g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the built-in one isn’t suited to your project. However for additional contacts, I would suggest using copper foil, and then solder a wire that connects from the foil pad to the breakout.

 

Health & safety

  • Ensure you are familiar with all H&S rules that apply to the environment you are working in.
  • Identify where first aid can be found in your work space
  • Keep all components dry and free from liquid spillages
  • To avoid static, make sure your work surface is sufficiently earthed
