RS485 Oxygen Concentration O₂ Sensor: Modbus RTU, Indoor Oxygen Concentration Detection, Oxygen Partial Pressure, Temperature and Barometric Pressure Monitoring

The RS485 Oxygen Concentration O2 Sensor is a high-precision, multi-parameter sensor designed for continuous oxygen monitoring. It is widely used in HVAC, laboratories, scientific research, indoor air monitoring, and environmental monitoring. The sensor measures oxygen concentration, oxygen partial pressure, temperature, and barometric pressure, with readings updated every second. Its non-electrochemical luminescence-quenching technology and long-life SST® O2 sensing element provide accurate and stable measurement across a 0–25% range. For easy integration, it supports RS485 Modbus RTU communication and low-power 9–28 V DC operation, while its IP50 wall-mounted design allows for convenient installation. Built-in surge, reverse-polarity, TVS, and ESD protection further enhance reliability during long-term operation.
