Description :

- The "Greenhouse Effect" is causing the Earth's ice to melt and create dangerous icebergs. - By measuring the concentration of CO2, we can take steps to reduce it and protect the Earth. - DFRobot has developed an Arduino-based CO2 sensor that can be used to detect CO2 levels. - The sensor uses an MG-811 module which is highly sensitive to CO2 and less sensitive to alcohol and CO, and has low humidity and temperature dependency. - The sensor has an onboard heating circuit to bring the best temperature for the sensor to function, and an internal power boosting circuit to 6V for optimal sensor performance. - The sensor also has an onboard conditioning circuit to amplify the output signal. - The sensor is easy to use with the Gravity Interface, which allows for plug-and-play connectivity, and is best used with the Arduino IO expansion shield. - DFRobot has also developed other CO2 sensors, including an Analog Infrared CO2 Sensor for Arduino (0-5000ppm) and a UART Infrared CO2 Sensor (0-50000ppm) for wider range and more precise measurements. - Applications: •Air Quality Control •Ferment Process Control •Room Temperature CO2 concentration Detection
