1PCS SCD40 SCD41 Gas Sensor Module Detects CO2 Carbon Dioxide Temperature and Humidity by I2C Communication(Green)

SensorsTransducersProduct introductionCarbon 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.featuresReference accuracy specified range 400-2000 ppmSupply voltage range: 2.4 5.5 VHigh accuracy: ± (40 ppm + 5%)Digital I2C interfaceIntegrated temperature and humidity sensor<;; 0.4 Ma average @ 5 V 1 meas/ 5 minutesInterface definition:1. GND: negative input port of power supply2. VDD: positive input port of power supply3. SCL: I2C clock port4. SDA: I2C data portSCD41 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 uup 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: 2.4-5.5VMeasurement range: 400 - 5000ppmAccuracy: ± (40 ppm + 5%) of the measured valueBus: I2CResponse: 60sRange (temperature): -10 - +60 ° CAccuracy (temperature): ± 0.8 ° C (for range 15 - 35 ° C)Range (humidity): 0
