Carbon Dioxide (C0²) Sensor for iSensor & iAccess Controllers
Carbon Dioxide Sensor: Monitor and Alert CO² Levels
The Advanced DataCentre Systems iSensor Carbon Dioxide sensor works directly with iSensor and iAccess Controllers. The sensing element gathers three essential metrics: CO², temperature, and humidity.
You connect the sensor using standard CAT5/6 Ethernet cable via an available sensor port. This simple setup provides a proactive solution to monitor the environment in data centres and server rooms.
Product Overview
How the CO² Sensor Works in a Data Centre
In a data centre, managing air quality and environmental conditions is critical. A carbon dioxide (CO²) sensor constantly monitors air quality. Rising CO² levels warn operators: air is stale, or ventilation is failing.
Here is the process:
- The sensor uses Non-Dispersive Infrared (NDIR) light to count CO² molecules.
- It converts these counts into an electrical signal.
- The building control system instantly reads this signal.
- The system acts fast. It boosts ventilation or alerts staff immediately.
- Operators use this historical data to optimise airflow. This step reduces energy waste and stabilises the entire environment.
By knowing the exact CO² concentration, your data centre avoids overheating, manages humidity, and efficiently controls fresh-air intake.
Practical Uses of a CO² Sensor in Your Data Centre
A CO² sensor does more than just track air quality. It actively improves your environment and operations in several keyways:
- Smart Ventilation: Use Carbon Dioxide readings to adjust airflow dynamically, reducing waste and improving efficiency.
- Cut Energy Costs: Don’t waste power on constant full ventilation. Adjust your systems based on real CO² needs, only when necessary.
- Prevent Hotspots: High CO² often signals poor airflow. Detecting it helps you spot and fix airflow issues early.
- Meet Safety Standards: Ensure healthy air for everyone. Carbon Dioxide monitoring helps you meet safety regulations and health guidelines.
- Predictive Maintenance: Watch CO² trends over time. This helps you anticipate when ventilation or filters need attention, preventing breakdowns.
- Make Informed Choices: Use sensor data to guide improvements. Back your decisions for upgrades or system changes with solid facts.
Temperature & Humidity Monitoring
The iSensor CO² sensor tracks Carbon Dioxide levels. It also accurately monitors temperature and humidity. Tracking these key metrics helps detect early problems. It spots signs of overheating, moisture build-up, and other environmental shifts. These issues can impact your IT equipment’s performance, reliability, and lifespan.
You install the Carbon Dioxide iSensor using a CAT5/6 Ethernet cable. This setup is similar to the standard Temperature/Humidity sensor. You can place the iSensor up to 500 meters from an iAccess or iSensor Controller.
Monitoring all environmental conditions gives you a complete picture of your data centre. This includes tracking air particles. A full view lets you react quickly when conditions change.
Installing and Maintaining Your Carbon Dioxide Sensor
Installation Steps
- Choose the right location — ideally where air circulates but away from direct airflow (vents) to get accurate readings.
- Mount securely: use the internal magnet to secure to the rack or metal object. Alternatively use other mounting methods as recommended by the manufacturer.
- Connect to a sensor port on the iAccess or iSensor Controller. The data can be managed via the on-board webserver or connected to your DCIM (Data Centre Infrastructure Management) or BMS (Building Management System.
- Once connected configure desired thresholds. If these are breached alerts will be issued.
Maintenance Tips
- Clean the Sensor: Dust and debris can affect readings — clean gently with a soft, dry cloth.
- Check Connections: Ensure power and data links remain stable, especially after physical work in the space.
- Review Data Trends: Regularly review Carbon Dioxide data to spot shifts or anomalies — this can also highlight sensor drift or faults.
- Calibration: Depending on your compliance or SLA requirements, periodic calibration may be necessary. Re-calibrate at intervals specified by the manufacturer to guarantee accuracy.
- Replace When Needed: Sensors have a lifespan. Replace them according to manufacturer guidance or when you notice persistent reading errors.
