Infrared proximity sensor made by Sharp. The sensor has a Japanese So. V at 150cm with a supply voltage between 4. We recommend purchasing the related pigtail below or soldering wires . A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.
The object being sensed is often referred to as the . This sensor SharpGP2Y0A21YK, boasts a small package and very low current consumption, takes a continuous distance reading and returns a corresponding analog voltage with a range of 10cm (4”) to 80cm (30”). This module features a fixed-gain, kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. We will illustrate the usage of the module with a NUCLEO-F103RB ( STM32F103) or Arduino UNO development board. Download the Demo code and extract it, then program the examples to your NUCLEO or Arduino development board.
A tutorial on How to make an InfraRed ( IR ) proximity sensor circuit along with detailed explanation on how the circuit works. Here I have shown a very simple IR circuit to make proximity sensor to detect an object. Acquire data using the DAQ Assistant which is provid. This light propagates through the air and once it hits an object it is reflected back towards the sensor. If the object is close, the reflected light will be stronger than if the object is further away.
The Sharp GP2Y0A02YK0F is a long range infrared proximity sensor with an analog output. Application Note – Introduction to IR Receiver Part Numbers. Circuit Description – Circuit Description of . IR proximity sensor report file.
CONTENTS DECLARATION CERTIFICATE ACKNOWLWEDGEMENTS 1. This digital infrared proximity sensor from Pololu detects objects between and cm. Its main characteristics are a quick response time, a small size, low current draw and a compact carrier PCB. Proximity Sensors are available at Mouser Electronics.
The principle of infrared distance sensors is based on the infrared light that is reflected from a surface when hitting an obstacle. An IR receiver will capture the reflected light and the voltage is measured based on the amount of light .
