Arduino laser counter, A detector can be any kind of sensor

Arduino laser counter, Want to create a smart visitor counter that tracks people entering and exiting a room? With just an Arduino board, and a pair of IR sensors. The code pasted below works, but it counts only one part as one. It is possible use a laser to count people but without using a reflector? That is, using only the laser and photodetector, both on the same microcontroller. I appreciate any help and I'll admit I'm still relatively new to arduino. I used this code from a youtube video so ir_pin was suppose to be an Jul 21, 2014 · Hello there! I've been reading about lasers in the forum but I still having a doubt. It needs to count 3 as one on the serial. They are usually placed in doorways and can be used to see how many people are in a room or a restaurant or a store at … Laser Counter In this project we are using Arduino Uno to count the number of boxes passing through by reading changes in LDR voltage drop along its terminals. Counting people is not that different from counting objects. For now we just need to know that we have two sensors and that each of them can tell us if a person is present or not. It has a wide range of applications including automatic parking slots monitoring , number of people entering / exi… Apr 30, 2020 · Arduino based RPM counter with a new and faster algorithm This project makes use of the preciseness of a laser beam, just one IR sensor and that good old arduino board to measure the RPM of motors.
