DIY – Fire Alarm Electricity Kit – Tested & Verified (Educational projects and learning DIY kit)

Product Description The DIY Fire Alarm Kit is an essential educational project designed to demonstrate how automated safety systems detect environmental changes. By utilizing a specialized heat sensor, this kit triggers a loud buzzer and a bright LED when exposed to a flame or high temperature. This "tested and verified" kit is a top choice for school science exhibitions, providing a practical look at how electronics can be used to protect lives and property.

Key Features

• Instant Heat Response: The alarm activates immediately when the heat sensor reaches its trigger temperature, simulating a real-world fire detector.

• Height-Adjustable Grill: Features a modular frame that allows you to adjust the distance between the heat source (like a candle) and the sensor for safe testing.

• Dual Feedback System: Includes both a high-decibel buzzer and a visual LED indicator to ensure the alert is unmistakable.

• Auto-Reset Logic: The buzzer will continue to blow until the heat sensor cools down, demonstrating the physical properties of thermal conductors.

• Pre-Verified Board: Includes a ready-to-use logic module that simplifies the wiring process, making it perfect for beginners and young hobbyists.

Technical Details

• Sensor Logic: The resistance of the thermal sensor changes as it heats up, allowing current to flow to the buzzer and LED once a specific threshold is reached.

• Battery Operation: Runs on a standard 9V battery, ensuring the project is completely portable and safe for indoor demonstrations.

• Hardware: Comes with a full set of nuts, bolts, and connecting strips for a sturdy mechanical assembly.
