SEN0219 Infrared CO2 Sensor Pinout and Projects

The SEN0219 Infrared CO2 Sensor is a compact and highly accurate sensor module that is designed to measure carbon dioxide (CO2) levels in the air. It is based on the non-dispersive infrared (NDIR) sensing technology and can measure CO2 concentrations in the range of 0 to 5000 ppm (parts per million).

The SEN0219 Infrared CO2 Sensor module consists of an IR light source, an IR detector, and a microcontroller that is used to control the sensor and process the measurement data. When the IR light passes through the air containing CO2, some of the light is absorbed by the CO2 molecules. The sensor detects the change in the intensity of the light that is received by the IR detector and uses it to determine the CO2 concentration in the air. This sensor module is easy to use and can be interfaced with microcontrollers or other digital circuits using a simple serial communication protocol. It also features a built-in temperature and humidity sensor, which can be used to compensate for changes in the environmental conditions and improve the accuracy of the CO2 measurements.

The SEN0219 Infrared CO2 Sensor module is commonly used in indoor air quality monitoring, greenhouse gas monitoring, and ventilation control systems. It provides accurate and reliable measurements of CO2 concentrations, which can help to improve the efficiency of heating and cooling systems and reduce energy costs. It can also be used in applications related to human comfort and health, such as monitoring CO2 levels in classrooms, offices, and other indoor spaces.
