A. The intelligent carbon dioxide detector uses an air semiconductor sensor to monitor the temperature and humidity in the air quality. B. It adopts an electrochemical detection module, which has relatively high precision and stable performance, and can detect the carbon dioxide value. C. It has relatively strong anti - interference ability, low power consumption and a relatively long service life. D. This product generally does not need calibration and can start detecting once it is powered on, detecting carbon dioxide. E. There are hundreds of ventilation holes on the back of the shell, which can accelerate the convection between the air and the machine to achieve detection, and also have a heat - dissipation effect. F. It has wide applications, such as agricultural planting, greenhouse vegetables, production warehouses, material processing, etc. G. Specifications: - Name: Air quality detector - Color: Black - Material: Plastic H. Packaging contents: - 1 carbon dioxide detector - 1 USB data cable - 1 English instruction manual I. It generally only includes the above packaging contents and does not include other products. J. Note: Light reflection and different displays may cause the color of the item to vary slightly from the actual product. The allowable measurement error is plus or minus 1 - 3 centimeters.
