Miniaturised CO/sub>2</sub> sensor
29 May 2019, Analogue, Mixed Signal, LSI
Thanks to new energy standards and better insulation, buildings have become increasingly energy efficient, but at the cost of accelerated deterioration in air quality. Since high CO2 levels compromise human health and productivity, CO2 is a key indicator for indoor air quality. Air exchangers and smart ventilating systems in the commercial and the residential sector use CO2 sensors to regulate ventilation in the most energy-efficient and human-friendly way.
Furthermore, CO2 sensors play an essential role for indoor air quality monitoring and can therefore be integrated in IAQ monitors, air purifiers and smart thermostats. Addressing these needs, Sensirion has developed the SCD40, a miniaturised CO2 and RH/T sensor that fits in a space of just one cubic centimetre. Based on the photoacoustic sensing principle, it is well suited for high-volume and cost-sensitive applications.
With dimensions of just 12 x 12 x 7 mm, the SCD40’s footprint has been shrunk by a factor of five compared to its predecessor, the SCD30. Using the photoacoustic sensing principle, the dimensions of the optical cavity are drastically reduced without compromising on sensor performance.
The integrated humidity and temperature sensor delivers two additional sensor outputs. The SCD40’s feature set thus makes it particularly relevant for CO2 sensing markets such as IoT, automotive, HVAC, appliances and consumer goods. |
