Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm)

SKU : A17003 INTRODUCTION The concentration of carbon dioxide (0.03% usuallly) is related to daily life. Recently, theres a study showing that the atmospheric CO2 content has reached 0.0385% (385 ppm) which is the highest value since 2.1 million years. The raise of atmospheric CO2 content to some extent results in global climate change. How to accurately measure the carbon dioxide gas concentration is becoming a universal research topic. DFRobot released its latest high-precision analog infrared CO2 sensor. The effectively measuring range is from 0 to 5000ppm. This sensor is based on non-dispersive infrared (NDIR) technology and has good selectivity and oxygen-free dependency. Besides, its service life could up to 5 years! It integrates temperature compensation and support DAC output. Most importantly, the product is easy to use; it is compatible with all types of microcontrollers such as Arduino with ADC function. FEATURES Waterproof and anti-corrosion High sensitivity Low power consumption Excellent stability Temperature compensation Excellent linear output High cycle life Anti-water vapor interference No poisoning SPECIFICATION Gas Detection: Carbon Dioxide Operating Voltage: 4.5 ~ 5.5V DC Average Current: 60mA @ 5V Peak Current: 150mA @ 5V Output Signal: Analog output (0.4 ~ 2V) Measuring Range: 0 ~ 5000ppm Accuracy: (50ppm + 3% reading) Preheating Time: 3min Response Time: 120s Operating Temperature: 0 ~ 50 Operating Humidity: 0 ~ 95% RH (no condensation) Service Life: 5 years Size: 37mm * 69mm weight: 34g
