Design of Carbon Monoxide (CO) and Smoke Sensor, and Creation of Warning System with Fixed Telephone Call Using These Sensors

A sensor system has been designed and realized, in order to prevent considerably the carbon monoxide (CO) gas poisoning, caused by the combustion of the substances containing hydro-carbon (HC) for heating purposes in our country. The system controls CO and smoke, which adversely affect human health. In the event of CO and smoke in the air, a fixed phone call warning system has been installed to alert the user.For CO sensor; The ash particles which was formed as a result of chemical synthesis of polypyrrole (Ppy), iron (III) chloride and acetic acid (CH3COOH) components, was compressed into a single piece by pressing with Hydraulic Press Machine. The electrical current conductivity was measured by the electrodes immersed in this monolithic product which its surface conductivity differs according to the ratio of CO in the air. Thus, the measurement of CO in any environment was able to be performed.For smoke sensor; A duct system was established to measure the density of smoke particles present in the atmosphere. Inside of this duct, a source of LED light, and a phototransistor system was placed in order to perceive the reflected rays emitted from this light source, by crashing to the smoke particles. And, the amount of reflected light connected to the smoke particles inside of the duct was measured. Thus, the measurement of smoke in any environment was able to be performed.
