The sensor monitors TVOC within a range of 0-10ppm (0.01ppm resolution) and O₃ (Ozone) within a range of 0-5ppm (0.01ppm resolution). It also measures temperature from -25 to 80℃ and humidity from 0 to 99.9%RH.
This device supports a wide range DC power supply of 12～48V as well as standard POE (Power over Ethernet) power supply, offering flexible installation choices for clean data transmission and power delivery.
The sensor is equipped with an RJ45 interface and supports multiple standard protocols including Modbus TCP, UDP, SNMP (V1, V2), and MQTT for seamless integration into various management systems.
It features comprehensive alerting options, including localized light and sound alarms, as well as remote email notifications and protocol-based alerts to ensure timely warnings.
The device has compact dimensions of 100*135*35mm and can be easily installed using either screw fixation or magnetic mounting, depending on your environment.
Yes, the sensor is designed with built-in data storage capable of keeping up to 100,000 logs, which can be viewed directly on the integrated 3.5-inch TFT color screen.
