CO2 Sensor Array

A CO2 Sensor Array is an integrated component within Industrial Systems that monitors and measures carbon dioxide concentrations across multiple points or zones. It provides critical environmental data for process control, safety monitoring, and regulatory compliance in industrial settings where CO2 levels must be maintained within specific operational parameters. The array typically consists of multiple individual CO2 sensors arranged in a spatial configuration, each using non-dispersive infrared (NDIR) technology. The sensors measure CO2 concentration by passing infrared light through a gas sample chamber; CO2 molecules absorb specific wavelengths, and the reduction in light intensity detected by a photodetector is proportional to the concentration. The array's control unit collects data from all sensors, processes the measurements, and outputs aggregated concentration data for the monitored area. This component is designed for integration into larger industrial systems, providing a centralized solution for multi-point CO2 monitoring. It is suitable for applications such as indoor air quality monitoring, ventilation control, and safety systems in facilities like manufacturing plants, laboratories, and greenhouses. The array's performance is characterized by parameters such as measurement range (0–5000 ppm), accuracy (±30 ppm at 25°C and 1013 hPa), response time (<30 s for 90% of step change), operating temperature (-10–50°C), operating humidity (0–95% RH non-condensing), supply voltage (3.3–5.5 V DC), power consumption (<20 mW average), output signal (I2C, UART), ingress protection (IP54–IP65 per IEC 60529), dimensions (20×15×5 mm), and weight (<5 g). These values are typical reference ranges and must be verified for the specific model and application. The array's materials include an infrared light source, photodetector, gas sample chamber, and signal processing circuitry. For procurement, it is essential to confirm model-specific specifications, calibration, and compliance with relevant standards with the legal manufacturer or supplier.

The CO2 Sensor Array operates through multiple individual CO2 sensors arranged in a spatial configuration. Each sensor typically uses non-dispersive infrared (NDIR) technology, where infrared light passes through a gas sample chamber. CO2 molecules absorb specific wavelengths of infrared light, and the reduction in light intensity detected by the sensor's photodetector is proportional to the CO2 concentration. The array's control unit collects data from all sensors, processes the measurements, and outputs aggregated concentration data for the monitored area.
