CO2 has a large impact on us, human activities, plants, and animals, basically everything on this planet. In agriculture, CO2 is vital for photosynthesis, and increases in CO2 concentration could be beneficial to certain crops such as wheat, rice, and soya beans, etc. [Source: Climate Change and World Agriculture] Whereas, a high CO2 level may cause asphyxiation to human and animals. The CO2 emissions trapped in the atmosphere is the main cause of global warming. CO2 also causes the ocean to become acid, which causes harm to life in the ocean. Hence, getting access to the data on the CO2 level is important. With the data available, we will know what actions to take in different circumstances.
This CO2 Sensor is a digital NDIR (nondispersive infrared) sensor based on the Sensirion SCD30 sensor module, which enables the highest accuracy in the measurement of CO2 level in the atmosphere continuously and accurately for long-term use. It's designed with a built-in calibration functionality, making it more accurate and reliable in measurement. We've also added a specially-designed PTFE filter which allows airflow and ensures fast response. It comes with UART and I2C interfaces, compact in size, can be easily integrated into various application scenarios.
This product also has two other sensors (humidity and temperature) on board. Please see the detailed specifications of each parameter below.
