Specifications Ultrasonic Oxygen Sensor Specifications Sensor Type Detection Method Detection Range① Ultrasonic Principle Detection Accuracy Detection Resolution Response Time Working Temperature Storage Temperature Working Voltage Average Working Current Life Span Remark① Oxygen concentration detection range 20.5%~95.6% is calibrated with PSA oxygen source. If use 99.99% pure oxygen as oxygen source, should add a coefficient to make a transfer, the formula is: Target concentration = (sensor reading * 1.142) - 3.42 Oxygen concentration detection range 20.5%-100% is calibrated with 99.99%...

Communication Protocol  UART Communication Protocol 1 Protocol overview 1) Baud rate:9600, DataBits: 8, StopBits: 1, Parity: No, Flow Control: No 2) The protocol data are hexadecimal data. For example, “46” is [70] in decimal; 3) [xx] is single byte data(unsigned,0-255); In double byte, the high byte is in front of low byte; 4) The default is active sending, and the sending cycle is 0.5 seconds. If you need to read more other data, send the corresponding command directly to the host, and the host responds immediately. 2 Serial communication protocol formats PC send format Start symbol...
