Product introduction
Carbon dioxide is a key indicator of indoor air quality to damage human cognitive ability and happiness. SCD40/SCD41 is the next -generation micro carbon dioxide sensor of Sensirion. SCD40/SCD41 has high accuracy and cost -effectiveness.And the communication foot leads.The temperature and humidity compensation on the film is to measure humidity and temperature measurement through the built -in temperature and humid sensor.SCD40/SCD41 can realize intelligent adjustment indoor ventilation systems according to the carbon dioxide concentration. Indoor air quality helps to maintain a healthy and efficient environment with low carbon dioxide concentration within a period of time.
