Advanced IAQ Sensor with Relay & Analog Output for Automation
Elevate your environmental control strategy with the Advanced IAQ
Sensor, engineered for intelligent indoor air quality management
and seamless automation. Designed for integration with smart
building systems, this sensor provides real-time monitoring of CO₂,
PM2.5, PM1.0, TVOCs, temperature, and humidity, with
precision-grade sensors and dynamic response capabilities.
Equipped with programmable relay outputs and analog outputs (0–10V
/ 4–20mA), the sensor can automatically trigger ventilation, air
purification, alarms, or HVAC system adjustments based on air
quality thresholds. Built for compatibility with BMS, HVAC, and
industrial control systems, it also features RS485 (Modbus RTU)
communication for smooth data exchange and system-wide
optimization.
Key Features:
Comprehensive IAQ Monitoring: Tracks CO₂, PM2.5, PM1.0, TVOCs,
temperature, and humidity
Relay & Analog Outputs: Control fans, dampers, purifiers, or
alarms automatically
RS485 Modbus Integration: Easy connection to building management
and automation systems
Flexible Output Configuration: Supports 0–10V or 4–20mA analog
signals for proportional control
Custom Threshold Settings: Trigger outputs when defined pollutant
levels are exceeded.
