The explosion-proof oxygen content monitoring equipment launched by Weichuan Technology is mainly used to monitor the oxygen concentration in the ambient air. This product adopts a high-precision oxygen gas detection sensor, which has stable and reliable data measurement, and the sensor has a small deviation in measurement values due to environmental changes. Using LoRa modulation and demodulation technology for long-distance communication, combined with the LoRaWAN protocol, it can quickly interface with third-party application platforms and be used for monitoring oxygen content in closed and semi closed environments, such as underground pipelines, to facilitate timely elimination of hazards and ensure the safety of life and property.
