SCD41 Gas Sensor Module 2-in-1 CO2 And Temperature Detection 12C Communication Sensirion Envi

product introduction

Carbon dioxide is a key indicator of indoor air quality, which harms human cognitive ability and happiness. SCD40/SCD41 is Sensirion's next-generation miniature carbon dioxide sensor. SCD41 has high precision and high cost performance. The module is arranged with a 2.54mm spacing pin interface leads out the power supply and communication pins. On-chip temperature and

humidity compensation realizes humidity and temperature measurement through built-in temperature and humidity sensors. SCD40/SCD41 can intelligently adjust indoor ventilation systems based on carbon dioxide concentration. Indoor air quality helps maintain a healthy and efficient environment with low carbon dioxide concentrations for a period of time.
