The Sensirion SCD40 CO2 sensor is used for indoor air quality applications

     Sensirion's deep expertise in miniaturized sensors makes this a breakthrough step in the field of CO(2) sensing. At 10.1 mm x10.1 mm x6.5 mm, the SCD40 is five times smaller than its predecessor, the SCD30. Using the principle of photoacoustic sensing, the size of optical cavity is greatly reduced without affecting the performance of the sensor.

     In addition, the SCD40 CO(2) and RH/T sensors take full advantage of Sensirion's superior environmental sensing expertise to provide two additional sensor outputs by integrating one high-quality humidity and temperature sensor. Due to its unmatched size and unprecedented value for money, the SCD40 is the sensor of choice for today's and future CO(2) sensing markets such as the Internet of Things, automotive, HVAC, appliances and consumer goods.

     Buildings are becoming more energy efficient thanks to new energy standards and better insulation, but at the cost of accelerating deterioration in air quality. Because high levels of CO(2) can harm human health and productivity, CO(2) is a key indicator of indoor air quality. Air exchangers and intelligent ventilation systems in the commercial and residential sectors use CO(2) sensors to regulate ventilation in the most energy efficient and humane way.

     In addition, CO(2) sensors play a vital role in indoor air quality monitoring and therefore can be integrated into IAQ monitors, air purifiers and smart thermostats. SCD40 Micro CO(2) and RH/T sensor solutions will revolutionize product design approaches and lay the foundation for a multitude of new applications.
