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 ...

But not so with this programmable IR ... the serial connection provided by its CP2104 chip. Using a simple plain-text control protocol, the user can modify the behavior of the device and monitor ...

The Pressure Sensor ... when the serial monitor is opened. This is a great building block for a future project using the Velostat or the RGB LED. It will also prepare the user on how to successfully ...

In security systems, they can be used to detect unauthorized access or to monitor pet movements. The IR Detector proximity sensor is designed to be compatible with both Arduino and Raspberry Pi ...

If you have ever wondered what the air quality is around living or work space, a new Instructables has been published that enables you to create a handy DIY Arduino air pollution monitor.
