Bare Conductive Capacitive Sensor

In these boards each electrode acts as a capacitive sensor.

Bare conductive capacitive sensor.

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. You can make make a simple capacitance sensor using a pad of electric paint an arduino and a resistor. At bare conductive we use capacitive sensing in our hardware such as the touch board pi cap and light up board. 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. The touch sensor is a powerful capacitive proximity sensor that sends a signal to the attached bits as you physically approach it. Bare conductive is a design and technology company producing an electrically conductive paint capacitive sensor hardware and a range of kits for making everything from interactive walls to musical instruments. 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.

Set up the touch board with the arduino ide. Use the grapher to visualise the sensitivity and precision of the touch board s capacitive sensors. The paint is a great solution if you want to quickly connect your electronic components together or draw your own creative interface. Ensure that bare conductive touch board is selected under tools board and that the correct serial cu port is selected under tools port.

Depending on how thick you apply the paint it takes about 15 minutes to dry. 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. How to set up the pi cap with a raspberry pi. The closer you get the higher the voltage it sends out.

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. Conductive targets include metal water blood acids bases and salt water. Discover how to set up the touch board with the arduino.
