Overview
This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in given time unit. LPO time is proportional to PM concentration.
This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.
Note: This sensor uses counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf.

This project introduces you to an engaging and cost-effective way with a laser dry target system. We'll utilize an Arduino Uno microcontroller as the brain of the system, interfacing with various components to create a realistic training experience. A laser pointer acts as your virtual firearm, while a light sensor (LDR) combined with an operational amplifier (LM358) precisely detects when the laser hits the designated target. A four-digit seven-segment display (TM1637) keeps track of your hits in real-time, motivating you to improve your accuracy. To add an auditory element to your training, a buzzer controlled by the Arduino will sound whenever you achieve a successful hit, providing instant feedback. Additionally, a reset button allows you to easily clear the counter and start fresh for a new training session. This DIY laser target system offers a safe and convenient method to hone your shooting skills at home, perfect for hobbyists and target practice enthusiasts.
