ADS21 Gas Sensor For Air Quality Monitoring Equipment Fresh Air System

ADS21 Gas Sensor For Air Quality Monitoring Equipment Fresh Air System

Product Features:

• High - precision Measurement: It can measure the concentration of carbon dioxide in the range of 400 - 5000 ppm, with an accuracy of ± (50 ppm + 5% of the reading value), which can provide relatively accurate carbon dioxide concentration information.
• Good Selectivity: Based on the non - dispersive infrared (NDIR) principle, it has good selectivity for carbon dioxide and is less affected by other gases, which can ensure the accuracy of carbon dioxide detection.
• No Oxygen Dependence: Unlike some gas sensors whose performance is affected by oxygen concentration, the ACD1100 has no oxygen dependence and can work stably in environments with different oxygen contents.
• Long Service Life: It has the advantage of a long service life, which can reduce the frequency of sensor replacement and maintenance costs.
• Digital Interface Output: With I2C/UART digital interface output, it is easy to connect with microcontrollers and other devices, which is convenient for data transmission and processing.
• Simple Structure and Flexible Use: It is a single - channel infrared carbon dioxide sensor with a simple internal structure, including a set of filters. It has a low cost and can be used flexibly, and can also be used together with other sensors to achieve multi - gas detection.

Product Uses:

• Air Quality Monitoring Equipment: It is used to detect the carbon dioxide concentration in the air to help users understand the air quality status. For example, in offices, shopping malls, schools and other public places, by monitoring the carbon dioxide concentration, it can be judged whether the ventilation is sufficient.
• Fresh Air System: It can be connected to the fresh air system. When the carbon dioxide concentration in the indoor air is too high, it can trigger the fresh air system to introduce outdoor fresh air to maintain a good indoor air environment.
• Air Purification Equipment: Some air purification equipment also uses this sensor to detect the carbon dioxide concentration in the air, and adjusts the working mode of the purifier according to the detection result to improve the purification effect.
• HVAC Refrigeration Equipment: In the HVAC refrigeration system, it is used to monitor the carbon dioxide concentration to optimize the operation of the system, improve energy efficiency, and ensure a comfortable indoor environment.
• Livestock Breeding: It can effectively monitor the carbon dioxide gas concentration in the farm, avoid the decrease of oxygen content in the air caused by high - concentration carbon dioxide, which may lead to chronic poisoning of livestock, and ensure their healthy growth.
