General Information

Buy online

The BM62S5602-1 is a detection module for the detection of oxygen concentration and flow in binary gas mixtures based on the ultrasonic detection technology. By detecting the forward and reverse flight time of the ultrasonic signal in the airflow tube and using the relevant algorithms, the oxygen concentration and flow value are output directly via the UART interface. The module integrates a temperature compensation function used to improve the module detection accuracy. The module has the characteristics of rapid response, high accuracy, factory calibration and long life.
