LoRaWAN dissolved oxygen sensor is a wireless dissolved oxygen sensor that uses fluorescence measurement principle. It is designed for scenarios such as outdoor, factory, aquaculture, etc. where power supply is inconvenient or scattered at multiple locations. Built in ER26500 lithium-ion battery (8500 mAh, 3.6V), combined with LoRa low-power communication technology, can achieve maintenance free operation for more than a year, truly solving the problems of difficult wiring and power supply in traditional wired monitoring.
1, Fluorescence method measurement, no oxygen consumption or calibration required
Using advanced optical fluorescence technology, the sensor measures the fluorescence quenching effect to invert the dissolved oxygen concentration, without consuming oxygen, and is not affected by flow rate and electromagnetic interference, making the measurement more stable. Supports a wide range of 0-20mg/L (0-200% saturation), with a resolution of up to 0.01mg/L and an accuracy of ± 3% FS. Coupled with high-precision temperature compensation of ± 0.5 ℃, it ensures the authenticity and reliability of the data.
2, Available in both freshwater and seawater versions, suitable for different water bodies
Provide two models, LDO (freshwater version) and LDOS (seawater version), optimized for freshwater environments (such as rivers, lakes, and tap water) and high salinity seawater environments (such as marine aquaculture and nearshore monitoring), respectively, to meet the precise monitoring needs of multiple scenarios.
3, Long life fluorescent film, easier to maintain
The lifespan of fluorescent film can reach one year under normal usage conditions, significantly reducing replacement frequency and backend maintenance costs. The sensor comes standard with a 5-meter cable by default (length can be customized), supporting a pressure resistance of 0.6Mpa, suitable for deep water or pipeline installation environments.
4, LoRaWAN wireless transmission, compatible with global frequency bands
Supports global mainstream LoRaWAN frequency bands such as CN470/IN865/EU868/US915/AU915/KR920/AS923, out of the box, can quickly connect to standard LoRa gateways and cloud platforms, and achieve remote real-time viewing of dissolved oxygen change trends, historical data playback, and threshold alarms.
5, Extremely low power consumption design, battery powered long-lasting durability
Excellent overall power consumption control, relying on LoRaWAN Class C mode and configurable reporting cycle (default 10 minutes), a single battery can support long-term field deployment without the need for external solar or mains power, making it particularly suitable for the construction of distributed water quality monitoring networks.
