Package List: 1 x CO2 Sensor Module Note: betweendiv>1. After the sensor is powered on, it needs to be preheated for about 20s to stabilize the measured data. Heating the sensor is normal since there is an electric heating wire inside, and if it is hot, it is considered abnormal.between/div>betweendiv>2. Avoid long term exposure to harsh environments. Whether the sensor is powered on or not, prolonged exposure to adverse environments such as high humidity, high temperature, and high pollution can seriously affect the performance of the sensor.between/div> Package List 1 x CO2 Sensor Module
