Automatic Fire Extinguisher Without Arduino | Inspire Science projects

Automatic Fire Extinguisher Without Arduino | Inspire Science projects

In this video, we build a fully working Automatic fire extinguisher system using just a flame sensor, 5V relay module, and mini water pump
all without Arduino! This is a super simple but powerful DIY electronics project that anyone can make at home using basic components and 2 x 18650 batteries.

✅ What You’ll Learn:
How fire detection works using flame sensor 🔥
How to trigger a relay directly from sensor output ⚡
How to control a water pump for fire safety 💧
How to make projects without Arduino or coding❌💻

✅ Components Used:
1 x Flame Sensor Module https://amzn.to/3TwIqF6
1 x 5V Relay Module https://amzn.to/4nEIdgP
1 x Mini Water Pump https://amzn.to/4leWD5G
2 x 18650 Li-ion Batteries with Holder https://amzn.to/462CzPh
Jumper Wires https://amzn.to/4lE2otA
Pipe/Tubing (for water spray) https://amzn.to/4leWD5G


💡 Working Principle:
When the flame sensor detects fire or high-intensity light, it sends a signal directly to the relay module, which then activates the water pump and sprays water on the fire. No Arduino or microcontroller is used – 100% direct wiring. ⚙️🧠

👨‍🔧 Great for:
