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 an infrared CO₂ transmitter?
An infrared CO₂ transmitter is a device that measures the concentration of carbon dioxide (CO₂) in the air and converts the measurement into a signal for monitoring, control, or data acquisition systems. It typically uses NDIR (Non-Dispersive Infrared) technology, which detects CO₂ based on its absorption of specific infrared wavelengths.
With features such as high sensitivity, low power consumption, stable performance, wide measurement ranges, and multiple output options such as RS485 Modbus, infrared CO₂ transmitters are suitable for industrial CO₂ monitoring, HVAC systems, indoor air-quality monitoring, greenhouse applications, ventilation systems, and environmental monitoring.
