Product introduction Carbon dioxide is a key indicator of indoor air quality, damaging human cognitive ability and happiness. 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. features Reference accuracy, specified range 400-2000 ppm Supply voltage range: 2.4 – 5.5 V High accuracy: ± (40 ppm + 5%) Digital I2C interface Integrated temperature and humidity sensor Low power operation to < 0.4 Ma average @ 5 V, 1 meas/ 5 minutes Interface definition: 1. GND: negative input port of power supply 2. VDD: positive input port of power supply 3. SCL: I2C clock port 4. SDA: I2C data port Board size: 13.4 × 21.6mm SCD41 can measure CO2 concentrations in the range from 400 to 5000 ppm. In addition to measuring CO2, the SCD41 can also measure temperature and humidity. The sensor communicates through an I2C address and can be powered from 2.4V up to 5.5V. You can connect it to both ESP32 or ESP8266 and duino Uno or Raspberry Pi. You can connect the module via a pin comb or our uŠup connector (JST-SH). The module itself also has its own pull-up resistors for the I2C bus. The module can be attached with 4 2.2x5mm screws. Specifications: Power supply: 2.4-5.5V Measurement range: 400 - 5000ppm Accuracy: ± (40 ppm + 5%) of the measured value Bus: I2C Response: 60s Range (temperature): -10 - 60 ° C Accuracy (temperature): ± 0.8 ° C (for range 15 - 35 ° C) Range (humidity): 0 - 100% RH Accuracy (humidity): ± 6% RH (15 ° C - 35 ° C, 20% RH - 65% RH) Dimensions: 21x21x8mm Weight: 2.5g
