The Grove CO2 & Temperature & Humidity Sensor SCD41 is a small but powerful module made by Sensirion. It is a multi-function sensor that can measure temperature, humidity, and CO2 at the same time. It is based on the SCD41 module and you can use this sensor in your GPS, IoT devices, or other devices which need those four parameters.
CO2 is a key indicator for indoor air quality as high levels compromise humans’ cognitive low power and well-being. The Grove CO2 & Temperature & Humidity Sensor SCD41 enables smart ventilation systems to regulate ventilation in the most energy-efficient and human-friendly way. Indoor air quality monitors and other connected devices based on the SCD41 can help maintain low CO2 concentrations and comfortable Temperature & Humidity for a healthy, productive environment.
