Best Science Project - 3 in 1 Safety Device || Gas Leakage, Alcohol & Smoke Detector without Arduino

Hello everyone, and welcome to our channel! In this video, we'll show you how to make a 3-in-1 safety device that can detect LPG gas leakage, alcohol, and smoke. It's an essential project that ensures the safety of your home or workspace.
For this project, you'll need the following components:
⦿ MQ2 sensor
⦿ BC557 transistor
⦿ Red LED
⦿ 5V buzzer
⦿ 100-ohm resistor
⦿ 470-ohm resistor
⦿ TP4056 charging module
⦿ Switch
⦿ 3.7V battery
---------------------------------------------------------------------
🔘Here's how it works:
When the 3-in-1 safety device comes in contact with LPG gas, alcohol vapors, or smoke, the MQ2 sensor detects their presence. The sensor triggers the BC557 transistor, which activates the alarm system consisting of the red LED and 5V buzzer. This immediate response alerts you to potential hazards, allowing you to take prompt action and ensure the safety of your environment.
This device is designed without using complex microcontrollers, making it accessible and easy to build. Our step-by-step instructions will guide you through the process, whether you're a beginner or an electronics enthusiast. This project is perfect for learning and practical application.
So gather your components, grab your tools, and let's dive into the creation of this invaluable 3-in-1 safety device. Together, we'll ensure a safer environment for everyone.

Can I use 5v for it without a battery ?

[@skr_electronics_lab]

Yes

[@sumaiyyasiddiqui2850]

At 2:17 secs of the video.... What pin have u used? And what is the aprox proce of that pin?

[@pubgtdm4832]

Mai 9v ka power supply use kr sakta hu kya
Please reply me

[@MegaTechno]

No it will probably destroy the sensor

[@saikatgain1421]

Led ka mejarment ketna hoga

[@bidhantalukdar6415]

Can i use mq4/mq5 gas sansor in this.project.pleas replay, this is arjent😢😢😢

[@bidhantalukdar6415]

Please reply😢😢😢😥😥😢😢🙏🙏🙏🙏🙏🙏🙏

No

[@dailyincome1749]

solar tracker project without arduino
Wala Work Nahi Kareah

[@skr_electronics_lab]

Bro check connection and use same components

[@Gamingtechworld]

Can I use mq3 sensor in this circuit ? please reply 🙇

[@skr_electronics_lab]

Mq3 sensor detects only alcohol

[@Gamingtechworld]

​@@skr_electronics_lab I need only alcohol detector 😅
