SCD40 CO2 and RH/T Micro Sensor Module

Sensirion's SCD40 sensor modules for IoT, automotive, HVAC, appliance and consumer products applications

Image of Sensirion CO2 and RH/T Micro Sensor Module SCD40 Sensirion has a long history in miniaturizing sensors and has achieved breakthroughs in CO2 sensing. Measuring only 12 mm x 12 mm x 7 mm, the SCD40 has a 5x smaller footprint than the previous SCD30. Using the principle of photoacoustic sensing, the size of the optical cavity can be drastically reduced without compromising the sensor performance. Additionally, the SCD40 CO2 RH/T sensor leverages Sensirion's outstanding environmental sensing expertise, combining high-quality humidity and temperature sensors to provide two additional sensor outputs. Due to its unmatched size and unprecedented price/performance ratio, the SCD40 is the sensor of choice for today and tomorrow for CO2 sensing markets such as IoT, automotive, HVAC, appliances and consumer products.

Buildings have become increasingly energy efficient thanks to new energy standards and better insulation, but at the cost of an accelerated deterioration in air quality. Because high CO2 levels can harm human health and productivity, CO2 is a key indicator of indoor air quality. Air exchangers and smart ventilation systems in commercial and residential sectors use CO2 sensors to regulate ventilation in the most energy-efficient and user-friendly way. Additionally, CO2 sensors play a vital role in indoor air quality monitoring and can therefore be integrated into IAQ monitors, air purifiers and smart thermostats. The SCD40 miniature CO2 RH/T sensor solution will revolutionize the approach to product design and provide the foundation for numerous new applications.
