Description

MQ7 Gas Sensor MQ-7 Carbon Monoxide in Pakistan

This MQ-7 Gas Sensor is able to detect Carbon Monoxide CO gas, a sensor widely used in safety and residential automation projects since this gas is highly toxic to humans. Its operation is simple, when the concentration of Carbon Monoxide is above the level adjusted by the potentiometer, the digital output D0UT is in high state, if below the level, it is in low state. To have a better resolution and measure the variation of gas concentration in the air just use the AOUT analog output and connect to an AD converter, such as the present one in Arduino and Raspberry Pi for example. NOTE: This MQ-7 sensor requires heating, so it is normal to heat and emit an initial odor.
