GAS/SMOKE DETECTION & CONTROL USING COOLING FAN DIY PROJECT ASSEMBLED KIT

Brief 
The project is a FULLY ASSEMBLED 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 Fan via relay. Fan will blow away smoke. 

Project Features
• Fully Assembled project kit
• Slide switch on/off control on board
• LM 358 based circuit
• Gas/Smoke Sensor 
• DC Cooling Fan interface
• 9V Battery Included 
• Includes Storage Box & Project Document
PCB DOES NOT CONTAIN ANY LOGO OR TRADEMARK, Hence can easily be used for school/college project purposes
