All-in-One Air Quality Transmitter with RS485 Modbus
Comprehensive air quality transmitter capable of detecting up to seven environmental parameters in real time. Features RS485 Modbus output, 3-colour LED air quality indicator, and optional display — ideal for smart buildings, offices, schools, and commercial complexes.
The All-in-One Air Quality Transmitter is a smart, multi-parameter monitoring device designed to measure up to seven key indoor air quality parameters, including temperature, humidity, CO₂, PM2.5, PM10, VOC, and formaldehyde. It provides accurate, stable, real-time data for HVAC control, environmental monitoring, and smart building systems.
Equipped with high-precision built-in sensors, the transmitter supports RS485 communication (isolated or non-isolated) with a Modbus-RTU protocol, enabling seamless integration with building automation and IoT platforms. The optional LCD display allows users to view multiple parameters simultaneously, while the three-colour LED indicator (green/yellow/red) provides an intuitive visual cue of current air quality status.
The unit includes wide-range power input, over-voltage protection, and reverse connection protection, ensuring long-term reliability in demanding commercial and public environments. Both indoor wall-mount and top-suction installation options are available for flexible deployment across various indoor applications.
