Infrared CO2 carbon dioxide sensor (0-50000ppm) SEN0220

brief introduction

The concentration of carbon dioxide is closely related to human life. The concentration of carbon dioxide in the air is about 0.03%, but the latest study shows that the content of carbon dioxide in the atmosphere has reached the highest value of 2 million 100 thousand years, that is, 385ppm, 0.0385%. Greenhouse gas effects, global warming and sea-level rise, these global climate changes are directly or indirectly related to carbon dioxide. How to measure carbon dioxide in the air accurately has become a universal research topic all over the world.

Recently launched a high-precision, wide range infrared carbon dioxide sensor with an effective range up to 0~50000ppm. The sensor is a universal and small sensor using non dispersive infrared.The principle of CO2 detection in air has good selectivity, no oxygen dependence and long life span of 5 years. And built in temperature compensation, the use of serial port, you can read the current CO2 gas concentration, the use is very simple, compatible with all kinds of single-chip and sensor.

The infrared sensor is a high performance sensor made by the mature infrared absorption gas detection technology. It has the characteristics of resistance to water vapor interference, no poisoning, long life and so on. It can be used in air for a long time to avoid prolonged heating after poisoning. It can be widely used in intelligent agriculture, HVAC and indoor air quality monitoring, industrial process and safety protection monitoring, agricultural and animal husbandry production process monitoring and so on.

This is a 0~50000ppm wide range of carbon dioxide sensors, using UART communication interface, suitable for Arduino, raspberry and other micro controllers. In addition, we also provide a 0~5000ppm range sensor that uses analog output, has higher precision, is fully compatible with our Gravity interface, and is more convenient to use.Infrared carbon dioxide sensor (0~5000 ppm)
