TOF or Time of flight is a commonly used method to measure the distance of distant objects by various distance measurement sensor like ultrasonic sensor ... of the medium such as composition or flow ...

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 ... that has been observed in front of the sensor. These ticks can be converted to a ...

By counting the pulses from the output of the sensor, we can easily calculate the water flow rate (in litre/hour – L/hr) using a suitable conversion formula. The Arduino Sketch (code) uses the ...

Arduino driver for the Pixart PMW3901 optical flow sensor. The driver is developed ... amount of movement that has been observed in front of the sensor. These ticks can be converted to a distance if ...

[Andy] demonstrates building an ultrasonic anemometer using a cheap after-market parking distance sensor kit and an Arduino. Demo video after the break. Aside from the price, these kits have the ...

To measure the pulses, we are going to use Arduino UNO. The pic below shows you the pinout of the water flow sensor. The water flow sensor circuit diagram is shown below to interface a water flow ...

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