The sensor continuously monitors Oxygen (O₂: 0-25%vol), Hydrogen Sulfide (H₂S: 0-100ppm), Temperature (-25～80℃), Humidity (0～99.9%RH), and Dew Point.
It supports a DC12～48V power input as well as POE (Power over Ethernet) power supply, communicating via a standard RJ45 interface.
The sensor supports multiple mainstream protocols including Modbus TCP, UDP, SNMP (V1, V2), and MQTT for seamless industrial integration.
The device features local sound and light alarms, and can also send email alerts and protocol-based notifications to remote monitoring systems.
It features built-in storage for up to 100,000 records. For installation, it supports both screw fixation and magnetic mounting options.
The sensor features a 3.5-inch TFT color screen for real-time readings, with compact overall dimensions of 100*135*35mm.
