Carbon monoxide (CO) generally referred to as the silent killer, arises from combustion of fuel with limited oxygen. This gas is a lighter than air and could be dangerous if inhaled in high quatity by humans. There is increase in the death rate yearly as a result carbon monoxide (CO) poisoning. To prevent this poisoning, it is important to build a detector that will assess the level of CO levels the room/environment so as to inform people of the CO concentrations level. The contructed device in this study was assembled using TGS 2442 sensor. It uses PIC16F917 microcontroller as the processor, in the configuration perform the task of converting the analogue input into a digital output which was shown on the LCD as the CO concentration in the room. The constructed circuit was used to determine the output voltage of CO emitted from petrol car, candle, diesel generator and petrol generator. Highest output voltage was obtained from candle light
