Bare Conductive Capacitive Sensor

Conductive targets include metal water blood acids bases and salt water.

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. Step 1 electric paint. 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.

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. There are two categories of targets that capacitive sensors can detect the first being conductive and the second is non conductive. How to set up the pi cap with a raspberry pi. At bare conductive we focus on making scalable smart surfaces and capacitive sensing is a foundational part of that vision.

The touch sensor is a powerful capacitive proximity sensor that sends a signal to the attached bits as you physically approach it. 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. Discover how to set up the touch board with the arduino.

The closer you get the higher the voltage it sends out. Depending on how thick you apply the paint it takes about 15 minutes to dry. These targets have a greater capacitance and a targets dielectric strength is immaterial. 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.

Electric paint is a water based paint that conducts electricity. Set up the touch board with the arduino ide. 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.
