SCD40 is the next generation of micro carbon dioxide sensor of Sensirion. SCD40 has high precision and high cost performance. The module leads out the power supply and communication pins with a 2.54mm spacing pin interface. On chip temperature and humidity compensation realizes humidity and temperature measurement through built-in temperature and humidity sensor. SCD40 can realize intelligent regulation of indoor ventilation system according to carbon dioxide concentration. Indoor air quality helps to maintain a healthy and efficient environment under low carbon dioxide concentration for a period of time.\u003cbr\u003efeatures\u003cbr\u003eReference accuracy, specified range 400-2000 ppm\u003cbr\u003eSupply voltage range: 2.4 – 5.5 V\u003cbr\u003eHigh accuracy: ± (40 ppm + 5%)\u003cbr\u003eDigital I2C interface\u003cbr\u003eIntegrated temperature and humidity sensor\u003cbr\u003eLow power operation to \u0026lt; 0.4 Ma average @ 5 V, 1 meas\/ 5 minutes\u003cbr\u003eInterface definition:\u003cbr\u003e1.
