Product Overview

Carbon monoxide (CO) leakage frequently occurs in metallurgical plants, gas facilities, power distribution rooms, chemical workshops, underground utility tunnels, boiler rooms and other sites. Being colorless and odorless, carbon monoxide causes rapid poisoning upon human inhalation and may lead to casualties in severe cases. Conventional manual inspection cannot achieve 24‑hour continuous monitoring; without instant early‑warning upon gas concentration exceeding limits, serious safety accidents are likely to happen.

The Haosheng industrial carbon monoxide toxic‑gas sensor adopts a high‑precision electrochemical sensing unit together with professional gas‑chamber structural design to collect real‑time carbon‑monoxide concentration in ambient air. Calibrated with exclusive compensation algorithms and multi‑point standard‑gas calibration, it delivers high measurement accuracy, good repeatability and stable long‑term operation. When concentration exceeds threshold, the device triggers local visual alarm and uploads data to third‑party monitoring systems via standard communication interfaces. It replaces fixed‑point manual inspection and realizes unattended online monitoring of toxic gas within plant areas.

Equipped with dual‑mode RS485 and WIFI by default, with 4G available for custom configuration. It complies with standard Modbus‑RTU protocol for seamless connection with various PLCs, industrial meters, configuration software and third‑party monitoring platforms, with no mandatory proprietary backend platform. The unit features an industrial‑grade wall‑mount waterproof housing with high protection performance for complex industrial conditions such as high temperature, high humidity and heavy dust. An optional high‑definition OLED screen enables direct on‑site reading of real‑time concentration for convenient commissioning and maintenance. Full‑range customization is supported for appearance, measuring range, communication protocols, packaging and more to satisfy project requirements across diverse industries.

Core Product Advantages

1. High‑precision Electrochemical Sensing for Accurate Low‑concentration Identification
   Adopts professional CO electrochemical sensor with high sensitivity and fast response to detect trace carbon‑monoxide leakage. Built‑in gas‑chamber liquid‑level‑linked acquisition logic distinguishes collection and analysis phases to prevent false alarms induced by water vapor and dust, ensuring stable drift‑free data over long‑term operation.
   
2. Wired / Wireless Dual Communication for Flexible Networking in Various Plants
   Standard RS485 Modbus‑RTU wired interface supports multiple sensors connected onto one single bus. Optional long‑range LoRa / LoRaWAN wireless communication works on industrial 433 / 470 MHz bands with strong wall‑penetrating capability. Bulk deployment without cabling is available for mountainous zones and large factories; both communication modes can operate simultaneously.
   
3. Dual‑level Protection: Local Visual Alarm plus Multi‑channel Remote Early‑warning
   Built‑in alarm indicator keeps steady lit when CO concentration exceeds threshold. Leakage alarms are simultaneously pushed to APP and SMS via backend platform. Manual reset is supported after fault elimination. Both on‑site staff and remote operation‑maintenance personnel receive hazard notifications for rapid disposal of toxic‑gas‑leakage risks.
   
4. Full‑parameter Visual PC Configuration Tool for Simplified Commissioning
   Dedicated host‑computer configuration software is provided. Connect the device via USB‑to‑RS485 adapter to modify device address, baud rate, data reporting interval, gas‑chamber threshold and CO alarm range with one‑click operations. Functions including parameter reading/saving and factory‑reset are supported to greatly improve batch‑commissioning efficiency.
   
5. Wide‑temperature Industrial Body for Stable Operation under Harsh Working Conditions
   Operating temperature ranges from ‑15℃ to +70℃ with humidity tolerance 0‑95%RH. It adapts to high‑temperature boiler rooms, humid underground utility tunnels and dusty metallurgical workshops. Compact standardized wall‑mount housing occupies minimal on‑site space.
   
6. End‑to‑end Customization for Integration with Third‑party Platforms
   Gas‑alarm thresholds, data‑upload intervals and LoRa communication frequency bands can be adjusted on request. Silk‑screen enterprise LOGO on housing and neutral export‑oriented packaging are available. Open standard Modbus protocols and LoRaWAN access parameters allow integration with self‑owned enterprise DCS, smart‑park and gas‑monitoring platforms.
   
7. Standard Complete Accessories for Fast On‑site Installation
   
8. Delivery includes certificate of conformity and warranty card. Wall‑mount structure requires few auxiliary materials. DC9‑30V wide‑voltage power supply is compatible with 24 V industrial DC power widely used in plants. A single electrician can complete installation and power‑on commissioning.
   

Communication & Integration Capabilities

This unit is a pure hardware data‑acquisition terminal with no binding to proprietary cloud platforms or mobile applications. It focuses on gas‑concentration acquisition and standardized data transmission to satisfy third‑party‑system integration requirements for various projects.

• Industrial‑site Integration: The RS485 interface complies with Modbus‑RTU with CRC check; baud rate adjustable within 1200‑115200 bps. Directly compatible with mainstream PLC, DCS, KingView, ForceControl and other configuration software for integration into existing industrial automatic‑control systems.
  
• IoT Platform Integration: WIFI/4G supports universal protocols such as MQTT and Modbus‑TCP for flexible connection to customer‑owned monitoring platforms, industry cloud platforms and data middle‑platforms. Data format and reporting cycle can be adjusted on demand.
  
• Data Transmission: Supports active reporting of real‑time concentration data and trigger‑based uploading of over‑limit alarms. Device operating status, measured values and abnormal alarms can be fully synchronized to connected systems.
  
• Parameter Configuration: Configuration software enables remote modification of device address, baud rate, calibration coefficients, alarm thresholds and other parameters to match networking and usage standards of different projects.
