Overview

The A/CO2-R2O-20K is a wall-mounted carbon dioxide sensor designed for indoor air quality monitoring with a measurement range of 0 to 2,000 ppm. It utilizes Non-Dispersive Infrared (NDIR) sensing technology and features a multi-output design compatible with 0-5 VDC, 0-10 VDC, and 4-20 mA systems. This specific model includes an override function for integrated HVAC control logic.

Why Choose This Part

The sensor features an Automatic Baseline Correction (ABC) algorithm that minimizes long-term drift and reduces the need for manual field calibration. It offers high flexibility for system integration by providing three simultaneous analog output signals and supporting both AC and DC supply voltages.

Applications

Demand Controlled Ventilation
Adjusting HVAC fresh air intake based on real-time CO2 levels to optimize energy efficiency and indoor air quality.
Commercial Office Spaces
Monitoring occupant-generated CO2 to maintain air freshness and cognitive performance in professional environments.
Classroom Environment Monitoring
Ensuring proper ventilation in schools to meet regulatory requirements and maintain a healthy learning environment.

Key Specifications

Type Carbon Dioxide (CO2)
Output 0V ~ 5V, 0V ~ 10V, 4mA ~ 20mA
Voltage - Supply 24VAC, 16.5VDC ~ 40VDC

Getting Started

Installation requires mounting the ABS plastic enclosure to a standard junction box and connecting a 16.5 to 40 VDC or 24 VAC power source. Configure the target controller to interpret the 12-bit resolution analog output across the 0 to 2,000 ppm range, and ensure the ABC algorithm has exposure to fresh air periodically for optimal self-calibration.
