Overview

The A/CO2-R2S-AN-A03-G5 is a high-performance wall-mount carbon dioxide sensor designed for indoor air quality monitoring. It utilizes Non-Dispersive Infrared (NDIR) technology to provide accurate CO2 measurements from 0 to 2,000 ppm with an integrated Automatic Baseline Correction (ABC) algorithm. This versatile transmitter supports multiple analog output signals including 4-20 mA, 0-5 VDC, and 0-10 VDC for seamless integration with building automation systems.

Why Choose This Part

The sensor offers exceptional flexibility with field-selectable 4-20 mA, 0-5 V, and 0-10 V outputs and is compatible with both 24 VAC and 16.5 to 40 VDC power supplies. The inclusion of the ABC algorithm ensures long-term stability by automatically adjusting for sensor drift in environments with periodic unoccupied periods.

Applications

Building Automation Systems (BAS)
Integrated into HVAC control loops to manage outdoor air intake based on occupancy levels for improved energy efficiency.
Demand Controlled Ventilation (DCV)
Used in commercial office spaces and classrooms to maintain indoor air quality while reducing fan and heating/cooling costs.
Greenhouse Monitoring
Ensures optimal CO2 concentrations for plant growth in controlled environment agriculture applications.
