Using a simple circuit to change the conductivity, the concentration of gas is converted to an equivalent output signal.
High - Low temperature cycle detection mode (1.5V heating) carbon monoxide detector, air increase and high temperature (5.0V heating) cleaning cryoadsorption with increased concentration of carbon monoxide gas in cast gas
Highly sensitive gas sensor for MQ-7 carbon monoxide is a low-cost sensor that can detect a variety of gas including carbon monoxide
