The invention provides a multifunctional integrated
oxygen sensor, which comprises a straight through
pipe, two ultrasonic probes and a control module, wherein the ultrasonic probes are arranged on the straight through
pipe, and are electrically connected with the control module, the control module comprises a main
control circuit, a pressure acquisition module, a temperature and
humidity detection module, a micro-
pressure detection module and a
wireless Bluetooth data transmission module, the main
control circuit is electrically connected with the pressure acquisition module, the temperature and
humidity detection module, the micro-
pressure detection module and the
wireless Bluetooth data transmission module, and the main
control circuit, the pressure acquisition module, the temperature and
humidity detection module, the micro-
pressure detection module and the
wireless Bluetooth data transmission module are integrated on the same circuit board. The multifunctional integrated
oxygen sensor has the functions of detecting the
oxygen concentration, the oxygen concentration and the temperature of the oxygen generator, detecting the pressure, the temperature and the humidity of the
oxygen storage tank, detecting the pressure of an air outlet and the like at the same time, multiple functions are integrated through the multifunctional integrated
oxygen sensor, and the manufacturing cost is reduced.
