make a simple ic 741 smoke detector circuit schematic diagram enclosed


Posted on Feb 5, 2014

A very simple to build smoke detector circuit has been discussed here through a schematic diagram, which can be easily built and installed over an area for the necessary detection purposes. The circuit incorporates the versatile FIGARO TGS 813 gas sensor as the main sensing device. The detections made by the sensor is translated into a logic status through a comparator stage composed of the IC 741. The generated warning signal is either integrated to a relay for triggering a fire control system or simply to a car siren for the required alarm..
