Bare Conductive Capacitive Sensor

Discover how to set up the touch board with the arduino.

Bare conductive capacitive sensor.

When correctly constructed this sensor can detect the presence of a person from up to 300 mm and can work behind any non conductive material such as glass wood plastic etc. In an electrical circuit you often find a resistor and a capacitor the resistor is a passive element in the circuit and the capacitor an active one. Conductive targets include metal water blood acids bases and salt water. Use the grapher to visualise the sensitivity and precision of the touch board s capacitive sensors.

Depending on how thick you apply the paint it takes about 15 minutes to dry. Make a capacitive sensor for arduino capacitive sensing is a great way to create touch and distance sensing interfaces that are low cost and that. There are two categories of targets that capacitive sensors can detect the first being conductive and the second is non conductive. These targets have a greater capacitance and a targets dielectric strength is immaterial.

Electric paint is a water based paint that conducts electricity. In these boards each electrode acts as a capacitive sensor. Set up the touch board with the arduino ide. Starting with our electric paint bare conductive has created tools which make prototyping smart surfaces easy from the very beginning our customers have used electric paint to create capacitive sensing on a diverse array of surfaces for an equally diverse set of use cases.

At bare conductive we focus on making scalable smart surfaces and capacitive sensing is a foundational part of that vision. Step 1 electric paint. At bare conductive we use capacitive sensing in our hardware such as the touch board pi cap and light up board. The paint is a great solution if you want to quickly connect your electronic components together or draw your own creative interface.

You can make make a simple capacitance sensor using a pad of electric paint an arduino and a resistor. The touch sensor is a powerful capacitive proximity sensor that sends a signal to the attached bits as you physically approach it. How to set up the pi cap with a raspberry pi.
