Simple LPG Gas Detector Alarm Circuit | Homemade Circuit ...

· The gas leakage alarm circuit uses a BC548 transistor to turn on the buzzer whenever LPG gas is detected by the sensor. Initially, when the circuit is turned on, the coil inside the sensor starts heating up and the current flow through the coil is controlled by a 33 ohms resistor while the zener diode makes sure that the voltage flow does not exceed

Carbon monoxide awareness Gas safety HSE

Carbon monoxide (CO) is a colourless, odourless, tasteless, poisonous gas produced by incomplete burning of carbonbased fuels, including gas, oil, wood and coal. Carbonbased fuels are safe to use. It is only when the fuel does not burn properly that excess CO is produced, which is poisonous. When CO enters the body, it prevents the blood from bringing oxygen to cells, tissues, and organs.
