Oxygen Concentration O2 Sensor Modbus RS485
Product description
The RS485 Oxygen Concentration Sensor uses luminescence-quenching optical technology to measure ambient oxygen partial pressure, oxygen concentration, temperature, and barometric pressure.
For easy system integration, it supports RS485 Modbus RTU communication. Its compact wall-mounted enclosure incorporates an SST O₂ sensing element with a service life of more than two years, ensuring high accuracy and excellent stability. The oxygen partial pressure range is 0-300mbar and oxygen concentration range is 0-25%.
The low-power 9–28 V DC operation, together with reverse-polarity, surge, TVS, and ESD protection, enhances reliability. The sensor is rated IP50 and is designed for indoor environments.
It is compatible with SenseCAP LoRaWAN Data Logger to connect with the LoRaWAN network for low-power and long-range wireless communication.
