Gas Sensor: This is the heart of the CO2 detector. GAO’s gas sensor is responsible for detecting the presence and concentration of CO2 gas in the air. There are various types of gas sensors used for CO2 detection, including infrared (IR) sensors, electrochemical sensors, and metal oxide semiconductor sensors. Each type operates based on different principles, but all are capable of detecting CO2 molecules in the air.

Microcontroller: GAO’s microcontroller serves as the brain of the CO2 detector. It receives input from the gas sensor, processes the data, and triggers appropriate actions based on predefined algorithms and thresholds. Our microcontroller also controls other components of the detector and communicates with external devices if necessary.

Display: Most of our CO2 detectors feature a display unit to provide real-time feedback on the CO2 concentration levels. Our display can be a simple LCD screen showing numerical values or a more sophisticated graphical display providing additional information such as trends, historical data, and alerts.

Alarm System: To alert users of potentially dangerous CO2 levels, our detector is equipped with an alarm system. Our system typically includes visual indicators such as LEDs (light-emitting diodes) and audible alarms such as buzzers or sirens. When our CO2 concentration exceeds predefined thresholds, the alarm system activates to warn occupants.

Power Supply: Our CO2 detectors require a power source to operate. Most of our detectors use either batteries or direct AC power. Our battery-powered detectors offer portability and can function during power outages, while our AC-powered detectors provide continuous operation without the need for battery replacements.

Communication Interface: Some of our CO2 detectors feature communication interfaces such as USB, Ethernet, or wireless protocols (e.g., wi-fi, Bluetooth) for data logging, remote monitoring, and integration with other systems or networks. Ours allows users to access CO2 concentration data remotely and receive alerts on their smartphones or other devices.

Enclosure: Our enclosure houses all the electronic components and provides protection against environmental factors such as dust, moisture, and physical damage. It also includes openings or vents to allow air to reach the gas sensor for accurate detection.

Calibration Mechanism: To maintain accuracy over time, our CO2 detectors often include calibration mechanisms. Our mechanisms allow users to calibrate the sensor periodically or in response to environmental changes to ensure precise and reliable CO2 measurements.

User Interface: Our user interface includes buttons, switches, or touch-sensitive controls for configuring settings, adjusting alarm thresholds, and performing other user interactions. Our interface makes the detector user-friendly and accessible to non-technical users.

Housing and Mounting Hardware: Depending on the application, our CO2 detectors may come with various housing options and mounting hardware for installation on walls, ceilings, or tabletops. We ensure proper placement for effective CO2 monitoring in different environments such as homes, offices, schools, and industrial facilities.
