Smoke Detector Using Arduino
1. Introduction About Project:
In this example, you will read the sensor analog output voltage and when the smoke reaches
a certain level, it will make sound a buzzer and a red LED will turn on.
When the output voltage is below that level, a green LED will be on.
2.Features:
1. Smoke detectors have auble alarms, visible alarms such as light-emitting diodes
(LEDs), or both.
2.They may also have an alarm output to a control unit.
3.Smoke detectors without a built-in alarm come with alarm contacts for output to an
external annunciator in the detector base, or to a control uni
3.Requirments:
Hardware:
1. Arduino UNO

2. Breadboard (generic)

Software:
1. operating system= window10.
2. ARDUINO IDE.
4.Advantages and Disadvantages:
•
Advantages:
1.
Smoke alarms save lives.
2. Smoke alarms that are properly installed and maintained play a vital role in reducing fire
deaths and injuries.
3. If there is a fire in your home, smoke spreads fast and you need smoke alarms to give you
time to get out
•
Disadvantages:
1.Very sensitive, which can lead to false alarms as a product of cooking.
2,Not as responsive to smoldering fires - they are minutes slower than photoelectric
sensors in detecting smoke particles from smoldering fires.
3.Use of radioactive material is a concern..
5.Existing system (feedback):
1.
Photoelectric sensors are set off when smoke enters the alarm and deflects a beam of light onto
a photocell.
2. For slow, smoky, smoldering fires, photoelectric alarms are far more sensitive and effective than
ionization alarms.
