MQ-7 Product Overview:
Sensitive material MQ-7 gas sensors used in clean air, low conductivity tin oxide (SnO2). High-low temperature cycling detection mode (1.5V heating) carbon monoxide detector, conductivity sensor with the increasing concentration of carbon monoxide gas in the air increases,high-temperature (5.0V heating) cleaning cryoadsorption stray gases. Using a simple circuit to change the conductivity, concentration of the gas is converted to the corresponding output signal. MQ-7 gas sensor of high sensitivity for carbon monoxide, this sensor can detect a variety of gases containing carbon monoxide, is a low-cost sensors for a variety of applications
Can be used for home and factory gas leakage monitoring devices, suitable for liquefied petroleum gas, butane, propane, methane, smoke, etc.
