MN-NCO2 Network CO2 monitor


Product Introduction

The MN-NCO2 network carbon dioxide monitor is a basic air quality sensor product independently developed by our company for detecting the concentration of carbon dioxide and CO2 in the environment. This product uses imported carbon dioxide sensing components and is based on non dispersive infrared (NDIR) spectral sensing technology to accurately measure the concentration of carbon dioxide in the environment.


Highlighted features

Supports multiple industrial standard communication protocols

Supports multiple communication protocols: The device supports various communication protocols such as SNMP, Modbus TCP, BACnet, MQTT, and supports multi scenario applications. We support the above protocols and can provide data in multiple ways simultaneously.

IoT Sensor: Can be integrated to AWS/Azure/Tuya IoT system directly with low cost.



Comprehensive SNMP Protocol Support

Supports SNMP v1/v2/v3 and SNMP Trap v2c/v3 with high security level.



Independent online notification function

Features email alerts and IFTTT smart integration, keeping you informed of critical changes anytime, anywhere!!
📩Email instant notification:
Once enabled, the system automatically sends email alerts when temperature or humidity exceeds your preset thresholds, ensuring immediate awareness and prompt action.
⚡IFTTT Internet Automation:
Beyond sending instant alerts to social platforms like Telegram and WhatsApp, it seamlessly integrates with smart home ecosystems including Google Assistant and Amazon Alexa. This enables fully automated control of connected devices - from air conditioners to humidifiers and fans - creating intelligent, internet-connected environments.



POE power supply

Pain points of traditional 485 bus data acquisition system:

1、The wiring is difficult to standardize, and there are easy connection problems between the wiring stage and the equipment installation stage, which requires high requirements for construction personnel.2、High post operation and maintenance costs: A device failure can affect the entire bus, increasing the cost of fault location and post maintenance.3、Distributed power supply, inconvenient for uninterrupted power supply.

The product supports POE power supply, solving the above pain points:

1、Standard wiring scheme: A single network cable can meet the needs of power supply and communication, and a standardized integrated wiring scheme can be adopted to reduce the requirements for construction personnel and minimize the connection problems during the wiring and installation stages.2、Isolation fault: Star structure fault isolation reduces the workload and cost of later maintenance.3、Centralized power supply: Simply provide uninterrupted power supply at the POE switch to ensure power supply to the collection system.
