This project uses an ultrasonic sensor to measure distances in centimeters and controls a set of LEDs based on those distances. The project is designed for Arduino boards, and you can use it to build ...

We used Ultrasonic sensor in many of our application to measure the distance: Arduino & Ultrasonic Sensor Based Distance Measurement; Measure Distance using Raspberry Pi and HCSR04 Ultrasonic Sensor; ...

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 ...

Arduino driver for the PAA5100JE and Pixart PMW3901(not tested atm) optical flow sensors. The driver was originally developed to support the Bitcraze Flow Breakout board. It communicates with the ...

A novel sensor, just announced by ifm, uses air flowing through a nozzle to measure the distance between the nozzle and a workpiece to a resolution of 5µm – about one-tenth the thickness of a human ...

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need … ...

Emergence of Controlled Environment Agriculture (CEA) ranging from computer controlled water irrigation system to lightning and ventilation has changed the conventional scenario of farming. This paper ...
