Q1: What is a CO2 sensor?
A1: A CO2 sensor is a device used to measure the concentration of carbon dioxide in the air. It converts the detected CO₂ concentration into an electrical signal that can be displayed or processed by a monitoring or control system. CO₂ sensors are widely used in indoor air quality monitoring, HVAC systems, industrial equipment, greenhouses, and environmental monitoring.
Q2: How does a CO2 sensor work?
A2: SISCO CO₂ sensors use infrared sensing technology, particularly Non-Dispersive Infrared (NDIR) technology. The sensor measures how much infrared light is absorbed by carbon dioxide molecules in the air. The amount of infrared absorption is related to the CO₂ concentration, allowing the sensor to calculate and output a corresponding reading.
Q3: Can a CO2 sensor be integrated into an existing system?
A3: Yes. Many CO₂ sensor modules are designed for integration into larger systems and electronic equipment. Depending on the specific model, available communication or output interfaces may include UART, PWM, analog output, or other digital interfaces. Users should check the sensor's specifications to ensure electrical and communication compatibility.
Tips: What is the difference between a CO2 sensor and a CO sensor?
A CO₂ sensor measures carbon dioxide, while a CO sensor measures carbon monoxide. Although their names are similar, they are different gases with different properties and applications. A CO₂ sensor should not be used as a substitute for a carbon monoxide detector.
