According to a press release from Sensirion, the SCD40 is the first miniaturized CO2 sensor. It is five times smaller than its predecessor. This extreme miniaturization was made possible by the photoacoustic sensing principle. In addition to CO2, the sensor delivers output on humidity and temperature. Due to its unprecedented price-performance ratio, Sensirion says the SCD40 is especially well suited for high-volume and cost-sensitive applications.
The new CO2 sensor can be used in areas such as the Internet of Things (IoT), the automotive industry, in heating, ventilation and air conditioning systems, household appliances and consumer goods. In buildings that are energy efficient due to better insulation, the sensor can help ensure good air quality. It can be integrated in indoor air quality monitors, air purifiers and smart thermostats, for example. Sensirion will be showcasing SCD40 at Sensor+Test 2019 in Nuremberg and at SensorsExpo 2019 in California.
Sensirion has its headquarters in Stäfa and is the world's leading manufacturer of digital microsensors and systems. The product range includes gas and liquid flow sensors, differential pressure and environmental sensors for the measurement of humidity and temperature, volatile organic compounds, CO2 and particulate matter.
