Wall Mount CO2 Transmitter

Wall Mount CO₂ Transmitter: The Smart Solution for Superior Air Quality

Ensure optimal indoor air quality (IAQ) with our state-of-the-art Wall Mount CO₂ Transmitter. Designed for seamless integration into both new and existing building management systems, this device provides precise, real-time monitoring of CO₂ levels, with optional sensors for temperature and humidity. By maintaining healthy indoor air, you can enhance the comfort, productivity, and well-being of occupants while improving your building's energy efficiency.

Key Features & Benefits

Our transmitter is engineered for flexibility, reliability, and ease of use, making it the ideal choice for schools, offices, hospitals, and commercial buildings.

• Real-Time Air Quality Monitoring: Utilizes a high-precision Non-Dispersive Infrared (NDIR) sensor to accurately measure CO₂ concentrations from 400 to 2,000 ppm, helping you meet ventilation standards and ensure a healthy indoor environment.
• Comprehensive Sensing: Go beyond CO₂ with an optional integrated sensor for temperature and humidity. An elegant OLED display provides at-a-glance readings of all measured parameters.
• Flexible Connectivity: Equipped with a Modbus RS485 interface and optional Wi-Fi, our transmitter offers versatile connectivity options. It integrates effortlessly with your existing Building Automation System (BAS) or HVAC controllers using standard protocols like MQTT or Modbus TCP.
• Intelligent Control: Features one or two configurable analog outputs for linear or PID control, allowing it to directly manage ventilation equipment. A built-in relay output adds another layer of control for fans or alarms.
• Enhanced Safety Features: An integrated audible buzzer and relay-triggered alarm can be configured to alert occupants and facility managers when CO₂ levels exceed predefined thresholds, ensuring immediate action is taken.
• Effortless Installation: The wall-mountable design is compatible with standard 65mm x 65mm electrical boxes and can be powered by 24VAC/VDC, making both new installations and retrofits quick and simple.
