SCD41 is the next generation of micro\r\ncarbon dioxide sensor of Sensirion. SCD41 has high precision and high\r\nperformance. The module leads out the power supply and communication pins with\r\na 2.54mm spacing pin interface. On chip temperature and humidity compensation\r\nrealizes humidity and temperature measurement through built-in temperature and\r\nhumidity sensor. SCD41 can realize intelligent regulation of indoor\r\nventilation system according to carbon dioxide concentration. Indoor air\r\nquality helps to maintain a healthy and efficient environment under low carbon\r\ndioxide concentration for a period of time. Features: Reference accuracy,\r\nspecified range SCD40:400-2000 ppm SCD41:400-5000 ppm Supply voltage range:\r\n2.4-5.5 V High accuracy: ± 5% Digital I2C interface Integrated temperature and\r\nhumidity sensor Low power operation to \u0026lt;0.4 Ma average @ 5 V, 1 meas\/ 5\r\nminutes Board size: 13.4 × 21.6mm Interface: 1.
