Product Description
 
GAS/SMOKE DETECTION & ALARM DIY PROJECT UNASSEMBLED KIT

Brief 
The project is a UNASSEMBLED KIT 
The project includes a small gas sensor board which is interfaced to other board with LM358 on it. The gas sensor senses the smoke and sends the signal to LM358 which will compare the signal voltage with a reference one. Based on a proper smoke signal, the IC will switch on the transistor which in turn will switch on the Alarm via relay. The alarm stops once the smoke fades away. 

UNASSEMBLED KIT CONTENTS
• Printed Circuit Board (which needs to be soldered)
• Electronic Components for the project
• Gas/Smoke Sensor
• DC Buzzer
• Project Document with Abstract, Circuit & Schematic (needed during soldering)
• Plastic Storage Box

PCB DOES NOT CONTAIN ANY LOGO OR TRADEMARK, Hence can easily be used for school/college project purposes
