Overview

The A/CO2-R2S-CP-A03-G5 is a wall-mounted carbon dioxide sensor designed for indoor air quality monitoring and demand-controlled ventilation. It utilizes Non-Dispersive Infrared (NDIR) technology to measure CO2 concentrations from 0 to 2,000 ppm with an accuracy of 3 percent. The unit supports flexible integration via triple-output options including 0-5 VDC, 0-10 VDC, and 4-20 mA signals.

Why Choose This Part

This sensor features an Automatic Baseline Correction (ABC) algorithm that reduces long-term drift and minimizes the need for manual calibration. It supports a wide supply voltage range from 16.5 to 40 VDC or 24 VAC, making it compatible with standard industrial and building automation power rails.

Applications

Demand Control Ventilation (DCV)
Optimizes HVAC system operation by adjusting fresh air intake based on real-time occupancy levels in schools or office buildings.
Commercial Building Management
Monitors air quality in high-occupancy areas such as auditoriums, gymnasiums, and shopping malls to ensure occupant comfort.
Economizer Control
Interfaces with building automation systems to manage energy efficiency by leveraging outdoor air when conditions are favorable.

Getting Started

Installation requires mounting the ABS plastic housing to a standard junction box and wiring to a 24 VAC/VDC power source. Select the desired output signal (0-5V, 0-10V, or 4-20mA) based on your PLC or controller's analog input configuration. Ensure the sensor is placed away from direct air vents or windows for accurate representative sampling.
