About this part
A compact module carrying an SCD40 or SCD41 sensor that measures carbon dioxide along with temperature and relative humidity, all read over I2C. It's built for indoor air-quality projects, such as a classroom CO2 monitor or a controller that switches on ventilation when CO2 levels rise.
- SCD40: 400 to 2000ppm, accuracy ±(50ppm + 5% of reading)
- SCD41: 400 to 5000ppm, accuracy ±(40ppm + 5% of reading)
- Humidity: 0 to 95% RH, typical accuracy 6% RH
- Built-in temperature and humidity sensing, which also compensates the CO2 reading
- Interface: I2C on a 2.54mm pin header
Choose the SCD41 for its wider range if you expect levels to climb past 2000ppm.

Type electronic module SCD40 SCD41 Gas Sensor Module Detects CO2 CO2 Temperature and Humidity Two In One I2C Communication Purple with Pin Array Product selling point: 1. With pin header 2. Using high-quality materials,the quality is guaranteed 3. High precision 4. Two-in-one temperature and humidity 5. The appearance of the product is exquisite and small Product introduction: Carbon dioxide is a key indicator of indoor air quality that damages human cognitive ability and happiness. SCD40/SCD41 is Sensirion's next-generation miniature carbon dioxide sensor. SCD40/SCD41 has high precision and high cost performance. The module is powered by a 2.54mm pitch pin header interface. The on-chip temperature and humidity compensation is realized by the built-in temperature and humidity sensor to achieve humidity and temperature measurement. The SCD40/SCD41 can intelligently adjust the indoor ventilation system according to the carbon dioxide concentration. The indoor air quality helps to reduce the carbon dioxide concentration for a period of time. Maintain a healthy,productive environment. Product parameters: SCD40: - COz measurement accuracy: ±(50 ppm +5% MV) - Measurement range: 400-2000 ppm - Accuracy: ±50 ppm - Relative humidity measurement range: 0-95%RH - Typical relative humidity accuracy: 6%RH SCD41: - COz measurement accuracy: ±(40 ppm +5% MV) - Measurement range: 400-5000 ppm (low power) - Accuracy: ±40ppm - Relative humidity measurement range: 0-95%RH - Typical relative humidity accuracy: 6%RH Product features: - Reference accuracy,specified range,SCD40: 400-2000 ppm SD41: 400-5000 ppm - Supply voltage range: 2.4–5.5 V - High precision: ±(40 ppm+5%) - Digital I2C interface - Integrated temperature and humidity sensor - Low power operation to Interface definition: 1.GND: negative power input port 2.VDD: Positive input port of power supply 3.SCL: I2C clock port 4.SDA: I2C data port Shipping list: Module X1 Pin header X1
