Feature

●-Z19C CO2 gas sensor (here, sensor) is a general purpose intelligent small sensor. It uses the principle of non-dispersion infrared (NDIR) to detect the presence of CO2 in the air
●Built-in temperature compensation: Serial output and PWM output at the same time, easy to use. This sensor is a high performance sensor created with a close combination of mature infrared absorbed gas detection technology and advanced optical circuit design and advanced circuit design
