INSIGNIA LABS GAS SMOKE DETECTOR & CONTROL KIT FOR SCHOOL COLLEGE PROJECT(Multicolor)

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.
