Distance Measurement Using Sharp IR Sensor with Arduino UNO

This project demonstrates how to measure distance using a Sharp IR sensor with an Arduino UNO. The sensor will read the distance to an object and print the value to the Serial Monitor. Connect the VCC ...

Linearize optical distance sensors with a voltage-to-frequency converter

A popular series of inexpensivedistance sensors integrates aninfrared emitting diode, a linearcharge-coupled-device array, and asignal-processing circuit in one unit.The output is a dc voltage, V S, ...

Parts: Analog Distance Sensors (Sharp GP2D12/2Y0A02)

Sharp GP2D12 and 2Y0A02 infrared rangers output a voltage proportionate to the distance of an object from the sensor. The GPD12 senses objects at a distance of 10-80cm, while the 2Y0A02 has twice the ...

Testing Distance Sensors

I’m working on a project involving the need to precisely move a tool based on the measured distance to an object. Okay, yeah, it’s a CNC mill. Anyway, I’d heard of time of fight sensors and decided to ...

Distance Measuring Sensors

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...
