Introduction

Air pollution is a growing concern in both indoor and outdoor environments. Harmful gases such as VOCs (Volatile Organic Compounds), formaldehyde, carbon monoxide (CO), and particulate matter (PM2.5/PM10) can significantly impact health and productivity. To address this challenge, EBYTE’s air quality monitoring and purification system integrates high-precision sensors, IoT connectivity, and intelligent control mechanisms to ensure clean and safe air.

Core Components of the Air Quality System

SM-VOC-P01 – High-Sensitivity VOC & Air Pollution Sensor

Key Features:

  • Detection Range: Formaldehyde, benzene, CO, ammonia, alcohol, cigarette smoke, and other VOCs

  • Output Signal: TTL UART (Modbus-RTU protocol) or 0-10 pollution level grading

  • Response Time: ≤20 seconds

  • Operating Voltage: DC 4.8V–5.3V (low power consumption, ≤60mA)

  • Environmental Resistance: Works at 0–50°C and ≤95% RH (humidity-resistant)

  • Compact Size: 32mm × 25mm × 15mm (easy integration into HVAC systems, air purifiers, and IoT devices)

Applications:

  • Smart air purifiers (automatic fan speed adjustment based on pollution levels)

  • HVAC systems (ventilation control in offices and factories)

  • Indoor air quality monitors (real-time alerts via mobile apps)

SM01-CH4A – Methane & Combustible Gas Detector

Key Features:

  • Detects: Methane (CH₄), hydrogen, and other combustible gases

  • Measurement Range: 0–10,000 ppm (or 0–20% LEL)

  • Response Time: ≤10 seconds

  • Alarm Threshold: Configurable (default: 4,000 ppm)

  • Long Lifespan: 5+ years (semiconductor sensor technology)

Applications:

  • Kitchen safety systems (gas leak detection)

  • Industrial gas monitoring (petrochemical plants, warehouses)

SM-CO-P01 – Carbon Monoxide (CO) Detection Module

Key Features:

  • Detection Method: Electrochemical sensor

  • Range: 0–1,000 ppm (resolution: 1 ppm)

  • Accuracy: ±50 ppm at 150 ppm

  • Lifespan: 10 years (maintenance-free operation)

Applications:

  • Smart home safety (CO alarms connected to ventilation systems)

  • Vehicle exhaust monitoring (garages, tunnels)

System Architecture & IoT Integration

 Real-Time Air Quality Monitoring

  • Multi-Sensor Network: Combines VOC, CO, PM2.5, and humidity sensors for comprehensive air analysis.

  • Modbus RTU/TCP Protocol: Enables seamless integration with PLCs, gateways, and cloud platforms.

  • Edge Computing: Local data processing to trigger immediate actions (e.g., activating air purifiers when pollution exceeds thresholds).

Smart Air Purification Control

  • Automated Fan Speed Adjustment: Based on real-time VOC/PM2.5 levels.

  • Cloud Connectivity: Data transmission to MQTT brokers (AWS IoT, AliCloud) for remote monitoring.

  • Mobile Alerts: Notifications via WeChat, SMS, or email when air quality deteriorates.
