Description

Carbon dioxide takes part in most of the activities on Earth, it has a huge impact on human activities and plants. A high concentration of carbon dioxide will be beneficial to an imperative activity of plants named photosynthesis. Under certain conditions, the concentration of carbon dioxide decides the level of photosynthesis and it directly shows the air quality. The emission of carbon dioxide also has a tremendous effect on global warming. 

    

CO2 Sensor is capable of great expectation of a long time using which can be a great character for saving cost and human resources. The character of high accuracy is able to eliminate the bias and reflect relatively precise data to get a correct reflection of CO2 level. With the protocol of UART and I2C, the data can be quickly transmitted to the server and it can be stalled to a variety of application scenarios. 

Sensor Hub Data Logger is an easy-to-deploy 4G cellular station. It uses the MODBUS-RTU RS485 protocol to communicate with sensors and can collect various sensor data simultaneously.   

Sensor Hub consists of 4 RS485 data channels. With extension hubs / RS485 splitters, it can connect with a maximum of 32 sensors at one time. The data is collected and sent to the cloud (either to the SenseCAP server or the client’s private server) via 4G/3G/2G (as shown below).

(Tips: The Sensor cannot be connected to the Sensor Hub. It can choose a RS485 CO2 Sensor.)
