New in the store – IR distance sensor w/cable (10cm-80cm)

Sharpdist Lrg
This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. Comes with 12″ long 3-JST interface wire. These sensors are good for short-range detection. For over 1 m distance, we suggest using sonar sensors

To use, connect black wire to ground, red wire to 5V and white wire to analog input. The analog voltage out will range from 3V when an object is only 4″ (10 cm) away and 0.4V when the object is 32″ (80 cm) away

For more information, please see the datasheet – and check it out in our store

Here’s a quick and simple project you can do with an Arduino, a breadboard, 2 servos and the IR distance sensor – a edge detecting robot!


#include "Servo.h"

Servo leftServo;  
Servo rightServo;  
int distSensor = 0; 

void setup() {  
  leftServo.attach(10);  
  rightServo.attach(9);
}   

void loop() {  
  distSensor = analogRead(0);
  if (distSensor 


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. what if there is an object closer that 10cm from the sensor? does it output higher voltages?

  2. the voltage goes back down when objects are closer than 10cm, see the datasheet for a graph
