Sketch for a capacitive proximity / touch sensor with Arduino. This sensor based on a square wave generator rather than charge time measurement as the popular CapSense library. This design results in ...

One of the most overlooked or forgotten proximity sensors on the market today is the capacitive sensor. Capacitive sensors are suitable for solving numerous applications. These sensors can be used to ...

You can use any resistor value between 100-kilo-ohm and 50-mega-ohm. Note that at higher resistor value, it behaves like a proximity sensor. The circuit requires a capacitive sensor library in Arduino ...

Capacitive proximity sensors include the measurement of human interference. Humans generally have a fixed coupling to earth. The device has a variable coupling to earth (in hand versus on table).

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, ... Arduino Capacitive Measurement Sensor.

This paper presents a measurement system with capacitive sensor connected to an open-source electronic platform Arduino Uno. A simple code was modified in the project, which ensures that the platform ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

In the application software, this sensor data is treated much the same as other input devices, such as a mouse, without worrying about decoding gestures and removing noise from the signals. Adding ...
